The opening of the Midway (Orange) Line in 1993 required 100 new cars. This, combined with the increasing age of the 6000s and a portion of the 2000s resulted in the January 1990 order for 256 cars from Morrison-Knudsen. The 3200s marked a return to the corrugated steel exterior of the 2200-series, supposedly to discourage graffiti. They included updated computer controls and control cab signaling. In anticipation of driver-only operation, full cabs are provided. (As of 1998, the whole system runs with only a single crewman per train.)
There are a slightly lower number of seats in the 3200-series cars when compared to other High-Performance Family cars, sacrificed for more standing space. Four of the transverse seats -- in the center of the car between the sets of side doors, two on each side -- are single seats rather than the standard double seats. The extra floor space provides more room for standees during rush hour. Like other modern cars, some seats near the doors face toward the aisle to accommodate equipment underneath. Altogether, of the 39 seats in the car, 15 seats face inward and 24 face forward or backward.
For the first time in decades, the new cars are equipped with both air conditioning and openable hopper windows in case the A/C fails. The 2200-series cars were retrofit with the hopper windows as well in their mid-life rehab circa 1990; the 2600-series cars received them in their mid-life rehab in the late 1990s and early 2000s. The computer components installed in the cars allow for some significant advancements in the cars' troubleshooting. The cars' microprocessor cam control group allows for the use of the General Electric-supplied Portable Test Unit (PTU) diagnostic system. The PTU allows a repairman to hook a laptop to a car, run a diagnostic, and quickly get a highly-detailed record of conditions and component status.
Cars 3441-3456, identical in all other ways to cars 3201-3440, were delivered with pantographs for the "Skokie Swift" Yellow Line. Later, the pantographs on cars 3451-56 were removed so the cars could be assigned to other lines that needed additional equipment; cars 3441-3450 continued to be pantograph-equipped for use on the Yellow Line until late 2004. On September of that year the Yellow Line was converted to third rail traction power and the pantographs became superfluous. The pans began to be removed from these 10 cars in late 2004 and the last came off in early 2005. However, all of the former pan-equipped cars (units 3441-56) retained the roof boards onto which the pantographs has been mounted.
The procurement of the 3200s allowed the retirement of the last of the 6000-series and nearly all the 2000-series cars. Cars 3201-3456 are used on the Brown, Yellow, and Orange Lines.
The CTA's Capital Improvement Plan included FY 2003-2007 funding for a light "C" overhaul (replacement of limited number of components) of the 3200-series cars and the beginning mid-life rehabilitation of the 3200s. Completion of the "C" light overhaul came in December 2004.
In mid-2004, the CTA modified a two-car 3200-series unit with a longitudinal seating arrangement on a test basis to test how additional maximum capacity could be attained with new seating configurations within existing car dimensions. Cars 3407-3408 were given a new interior seating plan with a longitudinal arrangement. To make up for the handgrips that were on the tops of the removed transverse seats, horizontal metal grip bars were installed overhead along each side of the aisle. In addition, vinyl straps were also installed in some places along the overhead stanchion and vertical metal poles were also located between every two seats. The CTA released the cars on Monday, May 17, 2004, first assigning them to the Brown Line before rotating them to a different line after about a week's time and surveying riders to ascertain their feelings, experiences, and preferences. The cars completed their test service on July 3, 2004 and were subsequently returned to their as-built seating configuration. To learn more about these cars, click on the gallery link below.
Rolling stock assigned to Skokie Swift service has traditionally been equipped with wheel scrubbers to enhance contact between the train's running gear and the track. Positive contact is essential to the operation of ATC cab signals and automatic grade crossing warning devices. Wheel scrubbers were applied to the original Skokie Swift single cars in 1964 primarily due to their light weight.
With the advent of longer trains and the heavier 3200-series cars in Yellow Line Skokie Swift service, the CTA began running tests to determine the future need for wheel scrubbers. To accomplish this, effective Monday, September 12, 2005 the first train to depart Howard every Monday morning was car 3457-58 or any Purple or Red line unit which are non-wheel scrubber equipped cars. The Maintenance Manager and Rail Supervisor then monitored the cars' operation and reported any ATC or grade crossing malfunctions to see if there is a noticeable problem with operations.
As of September 2005, all ten Yellow Line 3200-series -- cars 3441-3450 -- were equipped with wheel scrubbers. The test was concluded in late 2005 and a decision was made to remove the wheel scrubbers shortly after.
In Fall 2008, the CTA announced a pilot program to test three pairs of reduced-seating rail cars on the Brown Line in an effort to increase capacity. The reduced-seat cars were phased into service the afternoon of September 12, 2008, running only during peak periods on the Brown Line.
The changes were part of an effort by the CTA to accommodate an increase in ridership. Preliminary CTA numbers for August 2008 showed a ridership increase of 9.5 percent compared to August 2007. In hard numbers, that meant that 808,000 more train rides were taken in August 2008 compared to August 2007. For the year 2008, ridership was up 5.3 percent compared to 2007 as of the time of the cars' launch.
The high-capacity cars were dubbed MAX Cars, and six 3200-series cars were chosen for the pilot. The cars chosen were cars 3321-22, 3323-24, and 3325-26. The goal was to increase the floor space to allow more standees onto the car, thus increasing their carrying capacity. Because new railcars have a long lead time, this was seen as a fast, economical way to cope with increasing demand with the existing fleet of railcars. Twelve of the cars' 39 seats were removed in one of car in each pair, and 14 were removed in the other car to provide increased standing room. For every seat removed, CTA estimated that at least two riders can be accommodated. Additional stanchions and hand-hold straps were added to these cars for the safety and convenience of standing customers.
The six pilot railcars with reduced seats were clearly identified for riders before they boarded the train with large "MAX - High Capacity Car" decals located on both sides of the train's doors indicating they are reduced seating cars. The decals used white lettering on a dark yellow/gold background.
Although the CTA originally considered removing all the seats from designated cars, engineering tests determined that doing so could pose potential operational and safety issues. The specifications for the cars' original design designate a load of 22,500 pounds. CTA personnel tested the weight limits of the rail cars and determined that removing all the seats for standing customers would result in a weight increase that exceeds the specified design weight limits. While a railcar with all seats removed would still operate, stress would build up on the suspension and undercarriage and would result in reduction of the built in safety factors causing damage to the rail car body structure, suspension or undercarriage. Using a formula of estimated customer weight of 175 pounds per person, design capacity and floor spacing, personnel were able to determine how many seats could be safely removed without adversely affecting the suspension system. The cars with reduced seating are better able to manage the extra weight distribution. In addition, by leaving seats in the cars they are better able to accommodate riders who require priority seating such as seniors and expectant mothers.
CTA had developed plans for converting more 3200-series cars to MAX Cars, as well as a number of 2600-series cars assigned to the Red and Blue lines (the first and second highest ridership lines), if the pilot was successful. However, public reaction was negative -- although the cars did, in theory, reduce wait times at rush due passengers not being able to board packed trains by adding capacity, the perception of having less chance of getting a seat due to there being fewer of them was seen as a severe negative by many riders. The pilot ended, and no additional cars were converted. However, the six MAX Cars were not converted back and remain in their reduced-seating high-capacity form. The decals on their exteriors marking them as MAX Cars were removed circa 2010.
Security Cameras Installed
In February 2013, the CTA began to retrofit the 3200-series cars with security cameras. Four cameras capable of panning 360 degrees -- which provide the same amount of surveillance coverage as the seven cameras installed on the 5000-series railcars -- and one video recorder were installed on each 3200-series car, as well as every 2600-series rail cars.1 Due to their impending retirement, the older 2200- and 2400-series cars were not included in the program. The $13.9 million upgrades were funded by a federal Homeland Security grant. The installations were scheduled to be complete in September 2013.2
The CTA plans a mid-life overhaul of the 3200-series railcars to extend the life of the railcars and improve their performance, efficiency and reliability by replacing or rebuilding many of the cars' major components. The overhaul of the 3200s will replace many of the cars' major operating systems, including installation of new air conditioning systems and the rebuilding of the propulsion system (including motors and batteries), passenger door motors and the wheel and axle assemblies. In addition, wiring will be replaced, and springs and control equipment upgraded. Personnel at the CTA's Skokie Heavy Maintenance Facility will perform the overhaul work over the course of two-years, similar to the in-house mid-life the 2400-series cars received in the 1990s. The total estimated cost of the overhaul is $166 million.
Work to rebuild all 256 3200-series railcars is not expected to begin until 2015, but in 2013 the CTA started the process of procuring parts and operating systems that have long-lead times and require successful testing of pre-production samples.
On August 14, 2013, the Chicago Transit Board approved the award of two contracts that are part of the mid-life overhaul of the cars. The Board approved a $8.2 million contract to Ellcon National Inc. for the purchase of new auxiliary power systems that will be more efficient and reliable for the remaining years of service of the 3200-series cars.
A second contract valued at $4.1 million was awarded to Axion Technologies for the purchase of color light-emitting diode (LED) signs, which will replace the roller curtain destination signs on the sides and ends of each railcar. The LED destination signs will make the 3200s' signs consistent with those on the newer 5000-series cars.
In early May 2014, the CTA equipped two pairs of 3200-series cars assigned to the Orange and Brown lines with new LED destination signs for testing. The electronic sign units were installed on the front of the each car and on the outside and inside of the cars' sides.3 Like the LED signs on the 5000-series cars, the exterior signs are full-color, while the interior signs are amber. Cars with the LED signs can be run in train consists mixed with cars with the older roller curtain signs. The test installations were performed on Brown Line cars 3379-80 at Kimball Shop on May 7 and Orange Line cars 3207-08 at Midway Shop on May 8. The cars were run in service so that CTA engineers could monitor and analyze the installations' performance before conversion of the remaining cars begins. Starting in 2014, the CTA plans to equip all of its 256 3200-series cars with the LED signs.4
On September 10, 2014, the Chicago Transit Board approved the biggest component of the overhaul plan, a $92 million contract for the materials necessary to substantially renovate all 257 of the 3200-series cars. Components and materials procured under the contract include those for the propulsion and power systems, doors and door motors, wheel trucks, axles and motors, and new interior LED lighting.5
With the award on February 11, 2015 of a final contract for the upgrade of the cars' air conditioning units, everything needed for the rehab work was on hand or on order, 18 months after the decision was first announced. Rehab work will begin in March 2015, and the first rehabbed cars will begin appearing in service later in spring 2015. The overhaul will not disrupt service on the Brown and Orange lines, where the 3200-series cars are assigned, as only 16 cars will be worked on at a time. The work is expected to take about six weeks per car, and all 257 cars will be upgraded by 2017,6 two years earlier than officials earlier estimated.7
As part of the overhaul, the cab signal system on the 3200-series cars were modified with two key modifications. The first modification was the ability for the Allowable Speed of the Automatic Train Control (ATC) system to be set to, and enforce, a six (6) miles per hour speed limit. Prior to this modification, the lowest Allowable Speed setting was 15 mph. The other modification was the "Coast Contactor" function. The Coast Contactor function causes the propulsion system to go from propulsion to coast when the Allowable Speed is reached. This occurs automatically and requires no action to be taken by the Operator. If the actual train speed drops below the Allowable Speed, the propulsion system will re-engage and bring the train back up to the Allowable Speed. The Coast Contactor function is designed to reduce the possibility that the train will accelerate beyond the allowable speed, reducing the amount of manipulation of the master controller required between power and braking positions while operating. The first 3200-series rail cars modified were cars 3341-3342, in March 2017. They were used to demonstrate and instruct on this modification to the Cab Signal System.
Skokie Shops, where the 3200-series cars were being overhauled, was cut off from the rest of the CTA rail system for several months beginning on May 18, 2015, when part of the dirt embankment supporting the Yellow Line just east of Skokie Shops gave way during construction work by a contractor for the Metropolitan Water Reclamation District of Greater Chicago. The overhaul work continued to be performed at Skokie Shops during the disconnection from the rest of the system. Some 3200-series cars awaiting work had been sent to Skokie before the Yellow Line shutdown; others were trucked there until the Yellow Line reopened.8
