I have just been on the 700's to try them out, Wednesday 31st August, the trains were 700110 10.35 Three Bridges-Bedford, then 700114 13.40 Bedford-Brighton then 700114 again on 16.35 Brighton to Bedford, then I got 19.17 EMT Bedford to St Pancras.
The 700's look decent from the outside, interesting cab design and front, looks bit odd, but distinctive, the interiors are nice and spacious and airy, which different to other stock been on, which I really like, the seats were hard but for the 6 odd hours I sat on them were perfectly comfortable, having a socket, and table would be nice, I think they could have done a mixed fleet, table and sockets for outer suburban and like they are for inner suburban work, I like the PIS which a vast improvement on all other I have seen, was working properly on all the units I rode, I liked watching the loading info and toilet info, really informative. tried the toilets and found them to be perfectly up to standard for a modern train toilet, the door was handle rather than button which was nice touch.
I had wanted to see how they coped with heavy commuter loads in rush hour, which is what they are designed for, and I got my chance coming back from Brighton, it got rammed, the unit handled it with a plomb and brilliantly, it just swallowed up the crowds with ease, no feeling of being crushed like a sardine, space for people to stand, it loaded and un loaded really quickly, short dwell times.
The performance was like a proverbial stabbed rat, boy do they take off, they fly, would say quickest units off the mark I have been on, which helped keep to time, my maximum lateness all day was a couple of minutes, have to say I noticed they sway quite a bit, and was lively, especially under braking, which probably due to suspension needing bedding in, they didn't bounce just swayed side to side a bit, but very sprightly and fun to ride.
I think the 700's are well designed for what they are intended for, which is to handle heavy commuter loadings, quickly and efficiently, they are definitely people swallowers, and excel at it, a nice touch would have been tables and sockets especially as they do quite long journeys, the PIS is a big leap forward and to be applauded, I think they are very fit for purpose, and really good for what they are built to do, of corse in ideal world they could have had a few extra touches, and are not perfect but are a good effort in todays world, if I was to give a report card, I would give a solid B and with a few extra touches and slight retro fits could be an A.
