I'm trying to make some sense of the timetables / diagrams that are shown up by the latest FOI▸ disclosure and the On Line Journey planner - making sure I get my facts right before I shoot my mouth off.

In the May 2007 extra Melksham trains proposal , Class 153/8 would have formed Salisbury - Swindon services , instead of forming Southampton extensions of Westbury - Gloucester group services. The proposal would also have seen some Warminster extensions of Westbury - Gloucester group services diverted to Frome , in order to provide extra services there as well.
