The I11, a modern passenger coach of the SNCB was supplied to Belgian Railways in 1996 and 1997 at a level of 163 vehicles. Its new concept of interior space distribution and seating arrangement based on Bombardier's high-speed train technology and experience created a high level of comfort to passengers, drivers and supervising crew. At a speed of 200 km/h the coaches, identified by the SNCB (Belgian Railways) as I11, have a maximum noise level of only 65 dB(A). Other features making the vehicles attractive to the public are the air-conditioning, the comfortable seats and the indirect lighting system. Technical advantages are the secondary air suspension, the automatically operated interior doors and the passenger information displays inside, above the compartment doors, and on the outside of the coach. An area for wheelchairs as well as a toilet for disabled people is included to meet all of the passengers' needs and requirements.
