INTERFLEET Technology is carrying out testing of Alstom X40 and X60 trains being supplied to Sweden.

During June three weeks of dynamic testing were carried out on X40 double-deck EMUs for SJ inter-regional services, using instrumented wheelsets with accelerometers to assess the behaviour of a moving train.

’We go all over Sweden to find representative sections of track so that we can replicate all the situations the train might be exposed to’, said Interfleet’s test centre manager, Martin Bäfverfeldt.

Interfleet is carrying out pre-delivery testing in Germany of X60 suburban trains for Stockholm Transport. Acceptance testing will take place in Sweden during October and November, and the first of the trains will enter service in autumn 2005.
