Providing timetable information at stations

What sort of timetable / notice board should be provided at TransWilts stations, and what destinations should be shown?

The answer probably differs station by station - but for Chippenham and Swindon, the general departure boards showing key destinations, and the times of trains with arrivals there, simply need updating. When I last took a look, Melksham and Westbury were shown as destinations at Chippenham, but NOT Trowbridge! So - for both these stations I'll ask "please ensure that Melksham, Trowbridge and Westbury are included in the detination list". There is also a strng case for adding Salisbury and Weymouth. And in all cases, I think both through trains and single-change services which are not overtaken should be included.

At Melksham, the only timetable currently available is a line timetable for Portsmouth to Cardiff, which is very light on connections, and it won't even tell you about trains to Bath and Bristol via Chippenham. Something very different is needed, and I'm going to suggest using the same general departure board format as at Chippehham, showing train departures for (and arrivals at) the most popular destinations. And - for starters, I would suggest the following - to be sorted in alphabetic order as per usuaul for these posters:
a) Main service stations - SWI^» , CPM^» , TRO^» and WSB^»
b) To the south - DMH^▸ , WMN^» , SAL, SOU, PMH, FRO^» , YPM, WEY
c) To the west - BTH^» , BRI^» , FAW, WSM
d) To the east - RDG^▸ , PAD^»
e) To the north - OXF^» , CNM^»
These should fit on one standard sheet and I've tried to include the more common journeys along with a handful for "marketing purposes" - to remind people that such journeys are possible if they're reading the poster. CNM is there "for connections to the Midlands, North East, North West and Scotland". A discussion here this morning also wondered about including Cardiff, Birmingham, Bournemouth ... all of which we though "perhaps not", but I do wonder.

As a double sided handout, this Melksham sheet would be very useful with the RETURN journeys shown on the reverse. Has this ever been done?

For Trowbridge and Westbury, I don't yet have any suggestion as I'm not 100% familiar with what is there, nor are the others in the group that was discussing this a few hours back. Users / readers from there - comments welcome.
