Halogen lamps made for 12 to 24 volt operation have good light outputs, and the very compact filaments are particularly beneficial for optical control (see picture).

The main platform is defined to have a height of 1,100 mm (43.3 in) at a distance of 1,920 mm (75.6 in) from the center of the track to allow for trains with profile T. Low platforms at a height of 200 mm (7.9 in) may be placed at 1,745 mm (68.7 in) from the center of the track.
