A set of 4 cars is 72.12-metre (236 ft 7 + 3 ⁄ 8 in) long, 3.85-metre (12 ft 7 + 5 ⁄ 8 in) high and 2.80-metre (9 ft 2 + 1 ⁄ 4 in) wide. This is especially wide for a train that uses narrow gauge , for example vehicles of the large profile Berlin U-Bahn are only 2.65-meter (8 ft 8 + 3 ⁄ 8 in) wide, and they use the normal gauge of 1,435 ...
