The Class 648. The German Railroad, Inc.'s extensive procurement program encompasses several classes of modern diesel powered rail car trains. The DB AG's class 648 (LINT 41 / LINT 41H) is intended to replace the 628 in many places and make commuter routes more attractive for railroad passengers. The abbreviation LINT stands for "Lightweight Innovative Commuter Service Cars" in German. There are 2 versions of these streamlined, two-unit trains, with low platform and high platform steps. They offer seating for 16 in first class, 98 in second class, 15 fold-down seats, and 103 places for standing. The trains are well equipped with restrooms, ticket machines, and they offer entry ramps for handicapped people. The floor of these trains is lowered by 58 cm / 22-13/16" in the depressed floor area (78 cm / 30-11/16" on the LINT 41/H). The class 648 reaches a maximum speed of 120 km/h / 75 mph and can be coupled easily to other powered rail car trains by means of Scharfenberg couplers and used in multiple unit operation.
