SL X10p

X10p is a series of three-car electric multiple units operated by Greater Stockholm Transport (SL) on the Stockholm urban rail network called Roslagsbanan. The 891 mm (2 ft 11+3⁄32 in) gauged line cannot use the standard gauge rolling stock used in the rest of Stockholm, so SL ordered 35 new units to replace much older stock. Since 1995 X10p has been the sole stock used on Roslagsbanan.
