First Great Eastern says problems with the transformers on some of its new class 360 Desiro trains will not prevent it from running a full service. The rail firm reintroduced slam-door trains to cover the journeys affected by the withdrawal of around half its 21-strong, ?80m fleet. Around 55,000 people use the firm?s trains to travel to London?s Liverpool Street station each day. A spokesman for First Great Eastern said: ?There are suggestions that the technical problems with the new trains are resulting in cuts to services from Liverpool Street. This is simply not true and we plan to operate the normal service not just tonight but tomorrow, the day after and for the foreseeable future.?
