Someone on the SimSig forum has copied this list from the proposal document which suggests there should indeed be more trains on OTT than there currently are.
From the Proposal document

12:50 WAT - YVP via WSB, FRM, BRU & CLC (this will be an extension of a SAL service: forms the 15:50 to WAT)
13:50 WAT - YVP via GIL & YVJ (Extension of the 13:50 WAT - GIL, forms the 16:30 to YVJ)
14:51 YVJ - EXD (makes the Honiton Shuttle)
15:50 YVP to WAT via YVJ & GIL (extension of the 16:18 GIL - WAT)

16:55 YVJ - WAT via YVP, CLC, BRU, FRM & WSB (poss. extends 17:47 SAL - WAT or it would have to join an Exeter Train)
17:07 HON - EXD (presume this will join an existing Exeter to Waterloo
17:50 WAT - YVP via GIL & YVJ (extension of 17:50 WAT - YVJ, forms 20:30 to YVJ)
18:26 YVP - YVJ (makes an ECS to Salisbury at 18:45 via GIL)

20:30 YVP - YVJ (forms an ECS to Salisbury via Gillingham at 2147)
All of the above are a single class 159.

12:15 WRM - BMH (forms 14:55 WHM)
12:55 WEY - WAT via MDN, YVP, YVJ & SAL (not as yet sure which Salisbury service this will extend).
14:55 BMH - WRM (forms 16:26 WAT)
16:26 WRM - WAT (unsure what this forms afterwards, presumably tacked onto an existing WoE service).
16:55 WEY - WAT via MDN, YVP, YVJ & SAL (not as yet sure which Salisbury service this will extend).
All of the above are a single Class 159.
Sundays
16:25 GIL - WAT (new service, formed off ECS from Salisbury TMD, forms 18:45 Salisbury)
17:25 GIL - WAT (new service, formed off ECS from Salisbury TMD, forms 19:45 Salisbury)
18:45 WAT - SAL (new service)
19:45 WAT - SAL (new service)
Station codes (for anyone not aware):
BMH: Bournemouth | BRU: Bruton | CLC: Castle Cary | EXD: Exeter St. Davids | FRM: Frome | GIL: Gillingham (Dorset)
MDN: Maiden Newton | SAL: Salisbury WAT: London Waterloo | WEY: Weymouth | WRM: Wareham | WSB: Westbury
YVP: Yeovil PM | YVJ: Yeovil Jcn
Presuming this all comes off it will be good to see the Yeovil Junction - Yeovil Pen Mill spur returned to regular passenger use.
