Whilst there has long been a debate about whether this line should have been singled at all, I'm curious as to why the singling itself seemed to be done so badly. Two general principles of singling routes seem to be:
1. It's better to have loops in stations if possible, so trains can set down and pick up passengers whilst waiting. It also means trains aren't stopping in the middle of the countryside for a few minutes, which tends not to give the impression of a dynamic service.
2. It's prudent to have some flexibility, so that the timetable isn't entirely dependent on trains running to time and to allow insertion of extra trains if required.
The original 1967 layout was as follows. Mileages are approximate:
3 miles double track Exeter St Davids - Pinhoe.
12 miles single track Pinhoe - Honiton. Pinhoe had closed in 1966, so up trains could sit in an empty station awaiting a down train to pass.
Passing loop at Honiton
15 miles single track Honiton - Chard Junction
Passing loop at Chard Junction. Again this had closed previously.
21 miles single track Chard Junction - Sherborne
7 miles double track Sherborne - Templecombe. Templecombe had also closed in 1966, and the double track didn't (and still doesn't) extend into the station anyway.
6 miles single track Templecombe - Gillingham
Passing loop at Gillingham
19 miles single track Gillingham - Wilton South. Down trains might have to wait for up trains And again, Wilton South had closed in 1966.
3 miles double track Wilton South - Salisbury
That's four closed stations where trains could conceivably have to wait, whereas only three open stations - Honiton, Sherborne and Gillingham - had double track in situ.
The original plan proved unworkable, and Yeovil Junction - Sherborne was brought back into use later in 1967 as it hadn't yet been lifted. The other longest single line section between Gillingham and Wilton was eventually split by a loop at Tisbury - although this had to be placed outside the station as the down platform had been sold off, and this remains so today.
Other singling projects such as Kemble - Swindon, Oxted - Uckfield or the Cotswold Line seem to have been carried out more sensibly, albeit AIUI the double track ran out before Ascott-under-Wychwood prior to the 2011 redoubling. So why was Salisbury - Exeter poorly conceived?
The potential reasons I can think of are:
- There was a general belief at the time that the railways were in declined and all bar a handful would close, so there was little need for long-term planning.
- This was the first major singling project of its type and valuable lessons were learned for future projects.
- Operational convenience and cost. There are level crossings at Pinhoe and Chard Junction, so signal boxes presumably needed to be retained. It was cheaper taking platforms out of use and they could be sold off to private sector business.
- The Western Region management of the time wanted to ensure the Waterloo route was permanently downgraded. The conspiracy theorists favourite...
I've thrown in the last one as tradition, but I doubt it's fair - Gerry Fiennes indicates in 'I Tried to Run a Railway' that he did want the line to be run effectively, whereas he quite cheerfully indicates he wanted to see the Great Central closed a few chapters earlier. I suspect it's most likely a mixture of all three of the other reasons I've given. There might not have been a belief the line would close, but there certainly seems to have been a view that it was inconceivable traffic would increase to the extent the infrastructure would prove inadequate. I'd be interested to know if anyone has any other ideas / knowledge.
