The first two Bombardier Class 172 DMUs intended for London Overground services have reached the Old Dalby Test track where they are being run both singly and in pairs.rnThe unnumbered units are the first of eight which will take over from 150s on Gospel Oak to Barking services around June this year. The new trains resemble 170s but are fitted with bogies similar to those used under the Class 220 Voyagers.
