And the biggest pain in the !!!! to engineers today is the whole tendering and contractual process that is in place now that would have been much simpler and quicker in the 1930's

Yes - the public sector seems to spend half their budget on ensuring that they get good value for money...

But the same trend towards bigger documents, more planning (except for what actually goes wrong), and more cost in the contracts department has happened within the private sector. In some cases the company's structure and methods were set up for subcontracts within public contracts, but the impression I got was that this was seen as a more professional way of doing things.

A small update.  Things seem to be progressing to plan with just a couple of minor signalling design modifications so far.  Out of interest there is a track map showing the non-signalling changes at the top of the drawing here: https://www.oxford.gov.uk/download/downloads/id/1839/east_west_rail_b90505b-drg-pwy3003.pdf

Stage 2 commissioned to plan today (16 July 2018).  Trains running to/from London Paddington to Oxford and Cross Country to/from South only, using Platform No.4 at Oxford.  All other services still bus substitution.

Does the stage 2 cover all the reversible signalling to Didcot?

Given that we are told that it takes a long time for drivers to learn routes how are they trained with the new signalling (and there is lots of it) given that the first trains only ran today and were service trains?

The train crew have a 78 page briefing document which fully describes the new signalling.  Then its down to actual familiarisation on site once its commissioned.

As I understand it, the reversible signalling is not commissioned until Stage 3.

Yes, that's right.  All GWR drivers have (or will have) a briefing day to learn the many changes to signals and routes, and other TOC's/FOC's will have undertaken a similar approach.

I believe that the trains are using the new reversible signalling between Oxford's platform and Hinksey South Junction, but otherwise the full commissioning of all routes will be after next weekend.

I commented earlier that I didn't understand why the Paddington to Oxford services couldn't stop at Didcot Parkway and I am even more confused now because it appears that there are 3 services each way that do stop at Didcot that is the 0527, 0616 and 0709 from Didcot and the 0540, 0631, 0724 from Oxford.
 
So does anyone know why they are making us catch us a bus when it seems to be perfectly possible to run a train service?

Correct.  But I took the question to mean the reversible signalling to Didcot!  Between Hinksey South Junction and Oxford Platform No.4 trains are using the fully reversible signalled Down Oxford Main or Down Oxford Relief.
