In the light of the last few posts - what prospects of someone developing something better than the much-heralded machine that failed to deliver the goods on the GWML electrification to deliver OHL lines quicker and cheaper?

The "clever" people who dreamt up the OHL factory train have mostly left the industry, we now have engineer in the industry with recent experience who have learnt the lessons of GWEP especially from a number of former BR engineers who were involved in ECML etc that were brought in as consultants.

So how practically will the work be done at St Ives, when the line ends at the buffers at the station. An explanation would be welcome.

Probably not acceptable to Network Rail:

From another article it appears the Army's interest is that this is the railway that brings tanks into Catterick Garrison.
What I was looking for was the fabulous picture of an RE track laying machine on the Longmoor Military Railway, not to modern H&S standards but a typical Army pragmatic solution.

The sleeper laying train will work as close to the line end as it can, also when the Maidenhead - Bourne End was relayed last year the platform areas have concrete sleepers which were laid by RRV (Road Rail Vehicles) effectively track panel by track panel (60 ft ish)

There is plenty of video of the Plasser machine in action, including this piece in Sweden.

In the light of the last few posts - what prospects of someone developing something better than the much-heralded machine that failed to deliver the goods on the GWML electrification to deliver OHL lines quicker and cheaper?

It seemed to me at the time that the fault lay not with the OHL train but with whoever thought it was appropriate for the particular job in hand. I may well have this wrong and look forward to correction, but I recall that it worked according to what it said on the tin. There were lots of issues with stuff that had been buried along the lineside without being recorded, such as a massive internet outage when it punched a gantry base through a fibre optic cable, and signal cables being cut. Some of the tracks weren't in the same position as when someone last updated records, and we were left with exploratory digging having to be done by men with shovels. On a lovely virgin railway, with all the add-ons routed neatly through proper conduits, it might well have accomplished the claimed 1.6 Km per overnight shift, but the real world proved to be a more challenging environment. I would hope that we got our money back, but somehow, I doubt it..

Indeed so, I can just about see our favourite St Ives restaurant (Porthminster Beach Cafe) in the final shot!

Looks like the work is progressing well.

Thanks for posting, looks like quite a bit of new track is down already, including some with concrete sleepers.

Also interesting to see the latest large residence ("Skyfall") taking further shape on what I call "millionaires row" between St Ives and Carbis Bay, since I was last there back in August.

Interesting to see also what is being dug up on Porthminster Beach?

I note that although the whole line is seaward facing, that the apparent concrete sleepers shown in the video, appear to be on the most exposed stretch of the track being relaid. Reference to this aspect of the job was made earlier in this thread.

EDIT ...
