No it isn't, I've just realised that Clue 1 doesn't exclude the services from Melton Mowbray, as it only says to MMO, so go off this rewritten clue:
1. This station isn't served by direct services to or from Melton Mowbray
2. This station is served by EMT
3. This station is DfT Category F2
4. This station has two platforms
5. This station is run by Greater Anglia
