メトロポリタン線
The line used Metropolitan line A60 and A62 sub-surface rolling stock built by Cravens of Sheffield in two batches between 1960 and 1962. It was upgraded in 1994 with improved suspension, lighting, heating and ventilation. The rolling stock was regularly interchanged with that used on the main Metropolitan line and usually carried both East London and Metropolitan line maps, but ELL trains were four-car units with a driving cab at each end, unlike Metropolitan line trains, which, aside from the Chesham shuttle, ran as eight-car trains. Metropolitan line trains were mostly two single-ended units coupled together with fully operational driving cabs at each end: the Met could use any ELL trains, but the ELL could use only double-ended units.
