Useful site. I'm particularly interested to see that there is a regular train via the Wymington Deviation (MML slow lines avoiding Sharnbrook Summit) since I've never managed to do that section (about the only MML diversion I havn't done), and also once again a regular train booked to use the Ely avoiding curve (could have got that from a timetable, but I've not bothered looking since they stopped running that way a few years ago, and I didn't expect them to start again (I presume it's only used to keep drivers signed on the curve incase of diversions being required).
