OK fair comments lads. To be honest i was surprised at the DP2 derailments. Perhaps i got a dud, but a web search confirmed my opinion. I am glad to hear that not all Heljan are like this as it really was a nice model, great weight to it and detail, but I need trains that will run. As i said, the track radius is all 3rd and 4th, but the Heljan was throwing itself off at points and everywhere.
