Hi all. I cant seem to find a thread specifically about these trains so i thought i would start one. I just have a few questions. Where are the trains going to be built and tested? Is it Switzerland? I have heard a few different things about them being built and tested in the Czech Republic and in Romania as well. So I'm not entirely sure. Are the AGA Stadler Flirt trains going to be similar to the ones already in use in Europe (like the ones in Belarus / Estonia / Germany / Poland etc)? What will be the main differences? I ask because i know a lot of the mainland european models are completely different when they come to the UK (like our Siemens Desiro trains are completely different to the mainland europe versions). Is there any rough dates yet when they will first arrive in the UK and start testing? And then when they will first go in to passenger service? Also am i correct in thinking the trains will be numbered as follows? If so which ones will be allocated to which services? 745/0 - 12 coach 745/1 - 12 coach 755/3 - 3 coach 755/4 - 4 coach I can only find very little little information about the numberings so I'm not entirely sure. Finally whose idea was it to order three coaches trains? The current three coach trains around Norfolk and Suffolk already get very busy at times! So its not really doing anything to help overcrowding! Will there be an option to extend these to four coaches at some point? And will only having one set of doors per carriage have an impact? Will this increase boarding and alighting times? Personally i think it is an awful idea. Although they are wide double doors (thankfully they didn't go for narrow single doors) i think it will still just make boarding and alighting take much longer at stations. I would also be interested to hear others thoughts and views on these new trains. Many thanks.
