I've just been responding to a request for suggestions of journeys that need improvement and lines that should be re-opened from a national group.   Text reproduced here.  The cases seem to speak for themselves, don't they?

* Journeys in need of improvement -

1. The Transwilts line - West Wiltshire (Westbury, Trowbridge, Melksham) to Swindon.  There is a net outflow of 6000 employed people per day from West Wiltshire, and the largest town in the county, and with a major traffic flow to it, is Swindon.   The traffic flow clogs up the A350, with people who are communting by private car because the bus from Trowbridge takes 95 minutes, and the train (at 35 minutes) only runs two times a day - giving a Swindon arrival at 07:48 and a departure at 18:45 which is far too long for a pracical working day (the other service arrives at Swindon at 20:20, and leaves at 06:15)

2. Dilton Marsh - formerly set in the countryside, this station now sits between the growing residential communities of Dilton Marsh and Westbuy Leigh - each of which is just a few hundred yards away.  Plenty of trains pass through (and slowly too) but the services that stop are few and far between (with a huge peak hour gap in the evening)  and the service is horribly unbalanced.  Northbound many services run to Bath and Bristol, Southbound two of the few come from Swindon and some start at Westbury, and this means that round trip opportuunities from the residential area are currently fit only for the minority who are happy with waits, changes, and different ways out and back.

3. Melksham - a town of over 20,000 people, many of who travel daily to places like Swindon, Chippenham, Bath, Bristol and Trowbridge - all of which are rail linked - but which has just two services calling each way daily.

* Lines that should re-open

Frome to Radstock.   Track remains in place.   Radstock is a deprived area with commuting outflow and more houses being built (ironically on former railway land which may soon prevent an easy re-opening).   Some trains already terminate at Frome so there's a potential natural extension.

P.S. On rail fares ... try this one.  Swindon to Salisbury, single, catching the direct train via the TransWilts line (Chippenham - Melkshm - Trowbridge) at 06:15.   You'll be quoted 50 pounds for a journey that takes about an hour, and takes you 40 miles as the crow flies.
