The 14:04 Frome to Swindon is one of Frome's "phantom" services, unannounced on any of the timetable posters though it does come up of the LED display in the period leading up to its departure. I was there (to catch that train) on 20th May - so that's after the May timetable change. Poster space at stations is limited, and a full Cardiff - Portsmouth set takes up two panels. Frome has an extensive set of extra services not shown on existing boards, as fill-in services to help patch timetable gaps head off in a variety of different directions. From Monday to Friday, I think the following are all missing:
06:05 Paddington
06:45 Cardiff
14:04 Swindon
14:59 Warminster
15:31 Exeter (Fridays)
15:55 Paddington
20:15 Westbury
21:02 Westbury
and there's no easy current panel switch that would include all of those while leaving space for everything that's already shown on the current posters too.
The matter has been raised with
GWR▸ and the Heart of Wessex
CRP▸ , agreement reached between them that something which addresses the issues could (and will) be provided to coincide with the next annual timetable change. I'm afraid it's not just a switching around of current posters that exist, so it won't happen next week. or even next month.
In the meantime

Single fare 14.20 except
(1) - single fare 8.30; also serves Melksham
(2) - single fare 7.10; also serves Melksham
Slower journeys at lower fares. Connections with a single change at Westbury can also be made off the 08:02, 10:15 and 17:24 services from Frome at a single fare of 7.10, but these service arrive in Swindon 43 to 56 minutes later than the services via Bath Spa due to a long wait (very poor connection) at Westbury.
