They have been there since at least Tuesday.

Still not clear how they wil stop passengers going straight to P1 via the outside ramp (required for people with bikes, luggage,etc. as no lift), or using the side entrance or going to the Railway Centre.

Well I am sure it was 102 on the service I caught on Tuesday (17:06 ex OXF^» (Oxford - next trains)).

Another question, are these services being operated as Driver Only, and if so how can they react to a disabled person using the  alarm in the toilet particuarly when they are between stations?

I thought I would add my first experience of an Adelante (180102) which was interesting.
I caught the 17.06 Oxford to Paddington to Didcot, this service had previously been a 3 car turbo.
The train left Oxford 9 minutes late due to late running preceding trains and arrived at Didcot 20 minutes late due to several issues.
The first was just a general lack of passenger familiarisation, especially those with bicycles, leading to longer dwell times at Radley and Culham. Not sure that they should be used on these stoppers as a lot of bicycles are carried, a cyclist was left at Oxford due to lack of space and the bicycles loaded at Radley and Culham must have been placed in the vestibules.
The second issue was that it couldn't pull away from Radley and required the onboard staff  (fitters or instructors?) to fix/reset something before it could leave. Judging by their expression this may have been down to driver error rather than an issue with the train.
There also seemed to be an issue with the aircon which was working and great on a day like today compared with the normal non-aircon Turbo we have on this service, but it was still hot and I am sure there was heat coming out of the heaters, they certainly felt warm to touch.

But once they sort out the aircon and other teething issues they seem like a nice train to travel in and are certainly a lot smoother and quieter than the turbo.
