Thanks Dennis, very interesting. Do you know how many of the vehicles are still in Docklands colours, and when they are planning to change them to Essen yellow?
PS Just one small correction to the stock type - P89 Stock was vehicles 12-21 built by the ex-British Rail engineering company in York, England in 1989/90. Vehicles 01-11 were classed as P86 Stock and were built by LHB in Salzgitter, Germany in 1986.
I believe LHB adapted the DLR vehicles from one of their previous tram designs, and then licensed it for BREL to build the P89 in the VK.
