New DMU!

We welcomed some new rolling stock to the layout today, a Class 122 DMU. However there was something different about this DMU, although the lights came on there was no movement. Its an unpowered dummy in other words! The 122 DMU will be used as hauled stock to augment the (powered) DMU and also to re-enact stock transfers. The 122 looks great though has a problem with derailments but that looks like being caused by the coupler snagging on the buffers. By bending the coupling downwards slightly it seems to fix the problem though i still have more tests to perform.
