The Central Wales Line (as I still think of it) has some 1950s-and-on flat-bottom rail on assorted baseplates, with various clips and fastenings mixed up almost at random. At Llandrindod Wells station it's possible to see three adjacent sleepers with three different kinds of rail fixings (1950s elastic spikes, as in your top photo, 'curly' elastic spikes, and Pandrol clips).
The CWL has its own dedicated permanent way crew, based al Llandrindod Wells, and they do seem to operate on a like-for-like (or at least like-for-something-similar) repair basis. There's a compound next to the station platform where it's possible to see their stocks of rail fastenings, stacked up ready for use. It's like a museum of permanent way kit through the ages.
A while back I was interested to see they had a few brand new elastic spike baseplates, of the 1950s style - obviously new castings, very bright orange with the first flush of rust. So the older stuff is still manufactured if it's needed.
Much of the CWL is bullhead track, which again seems to be maintained on a like-for-like basis. Some of it is in very good condition, clean ballast with tidy shoulders. But there are a few less-good areas which never seem to get any attention. I took this photo at Builth Wells station, adjacent to the platform...quite a daunting sight for passengers. I suppose it's good enough for the lightweight DMUs which operate most of the services, but the line is also used quite frequently by steam charters. Imagine a Black Five hammering over this bit of track...
Note non-standard keys, apparently an experimental type, never widely used. See what I mean about the museum of permanent way!
