Though they had a design maximum speed of 100 km/h (62 mph), experience showed that they did not ride well when travelling at speeds over 40 km/h (25 mph) and so henceforth were limited to that speed. They were numbered E401–E419, and were withdrawn from service between 1968 and 1977 and none were preserved.[1]

Model

The E401 was available as a resin model from "Q Kits",[2] but this company is no longer trading as the owner has retired.

A 401 Body is now available from Shapeways via Valvedesigns (a Rapid Prototyping Service)[3]
