The main static profile T allows for a maximum width of 3,750 mm (12 ft 3.6 in) rising to a maximum height of 5,300 mm (17 ft 4.7 in). The profile Tc allows that width only at a height of 3,000 mm (9 ft 10.1 in), requiring a maximum of 3,400 mm (11 ft 1.9 in) below 1,270 mm (50.0 in), which matches with the standard for train platforms (with a height of 1,100 mm [43.3 in]). The profile Tpr has the same lower frame requirement but reduces the maximum upper body width to 3,500 mm (11 ft 5.8 in). The more universal profile 1-T has the complete body at a maximum width of 3,400 mm (11 ft 1.9 in) still rising to a height of 5,300 mm (17 ft 4.7 in).
[57] Exceptions shall be double-stacking, maximum height shall be 6,150 mm (20 ft 2.1 in) or 6,400 mm (21 ft 0 in).
