I've just had a go on 211. It looks rather like what would happen if a B92 was crossbred with an old Tyne and Wear Metrocar, but it's not bad. When they were originally on test I saw some videos of them and the doors looked painfully slow to close - they're not at Class 165/166 guillotine levels, but they're certainly a lot quicker to close now! The seats were essentially breeze blocks in a moquette coat but I'm sure they'll soften over time. The last thing I noticed (I was in the leading coach), and the only thing which really concerned me, was some quite severe lateral oscillation entering stations, but I was only on it from Canning Town to West Ham so maybe it was something else. Overall, I was pleasantly surprised
