I like to keep lists, this might help those interested in modelling the Mk3SD. Of course, until Hornby announce the actual coach numbers, we cannot really know for sure what 'set' to order. The GWR GW01-11 are pretty much fixed, with spares swapping within the sets. CrossCountry have several spares and shall swap these around maintenance, below are current formations. Scotrail are a little more fixed, with spares available.    CrossCountry  operate 2+7 and not the 2+9 Hornby are curren
