Bombardier Talent

The Talent is a multiple unit railcar manufactured by Bombardier that was developed by Waggonfabrik Talbot in Aachen shortly before the company was acquired by Bombardier in 1995. The name "Talent" is an acronym in German for "TALbot LEichter Nahverkehrs-Triebwagen" (in English, "Talbot light suburban railcar").
It comes in a number of variants, including high-floor, low-floor, diesel-mechanical, diesel-hydraulic, diesel-electric, electric, and tilting, and in lengths of two, three, or four carriages. As with most multiple-unit trains, Talent units can run individually, or be coupled together to form longer trains.
Specifications.
Classified as heavy rail according to UIC standards, the Talent is a two-, three- or four-part articulated railcar with Jacobs bogies. Partially as a result of this, the interior of an entire unit is essentially a single, long cabin; it is possible to see or walk from end to end without opening doors or passing through narrower gangways. The sharing of bogies also means that a Talent unit cannot be easily disassembled or rearranged without the assistance of a railway yard. In those variants whose floor is above the rails, this means that the articulation floor is raised, but with ramp access, since it needs to be higher than the wheel diameter, above rail level. In the variants with floor height, the floor is flat from the first door to the last. The endsections have a raised floor in all variants, because the traction equipment installed underneath requires more space than unpowered bogies. The optional tilting system (called ContRoll) is unique: no swinging bolster is required between the bogie and the car body, but hydraulic cylinders, fitted between the anti roll bar system and the carbody, directly actuate the tilting.
Service.
After a prototype was presented in 1994, the first Talents entered service in 1996. They are used by mainline railways in Germany, Austria and Norway. More than 260 are in service worldwide.
In a more unusual use, three diesel Talents identical to Deutsche Bahn's class 643 once formed the fleet for Ottawa's O-Train Trillium Line, a diesel light rail transit line running entirely within the City of Ottawa. The Trillium Line shares a lightly used freight railway line. As the Talent is not certified for concurrent shared-track operation with freight trains in North America, freight traffic is not permitted on the Trillium Line's route while passenger services are running. Although it is still legally classified as a main-line railway, Transport Canada allow the O-Train Trillium Line to use One-Person Train Operation, with fares collected through a proof-of-payment system. In March 2015, all three Talent units were replaced by Alstom Coradia LINT diesel units.
The Talent has now been superseded by the Bombardier Talent 2 and Talent 3.
