 They have a different interior more suitable for regional traffic and are slightly heavier and have toilets (X10 don't have them since most SL stations have toilets).From 1999 only 52 X10 remained and all of them belonged to Storstockholms Lokaltrafik (SL).They were refurbished with new interiors and repainted between 1998 and 2002

Two other variants are X12 and X14 which can reach a top speed of 160 km/h.
