The 1995 Stock shares many features with the 1996 Stock found on the Jubilee Line, and indeed both types were built by Alstom in Birmingham. The 1995 and 1996 Stock have different seating layouts and cab designs, and 1996 Stock trains are designed as seven-car trains. Despite the 1995 Stock designation, the step-plates found on the trains read '1996'. It is believed that the 1995 designation served solely to distinguish this stock from the similar stock on the Jubilee Line. Like the 1996 Stock, the trains were fitted with passenger operated door-open controls from new, but these are disabled.
