Lets hope TFL & MTR Crossrail start getting there butts into gear more and start getting these trains out into revenue earning service as only thing i understand holding them back is the fact TFL Rail drivers havent been taught how to drive them, urm, thats the TOCs responsibility to ensure that happens and if not, why is TFL not holding MTR Crossrail to account for delaying the new trains introduction so the 315s can finally bugger off the GEML Metro routes, passengers have seen the 345s whizzing up and down from LST to SFD yet cant board them as are being tested by NR staff and not TFL Rail (Franchisee MTR Crossrail) staff and it is wrong, if MTR are incapable of sorting this out now then how will they cope when they get the GWML Heathrow Connect Services next year, if they cant get these trains out by the end of June then TFL should put the franchise up for bidding and MTR banned from bidding
I'm pretty sure not introducing new rolling stock onto a railway line before it's ready is the right thing to do. As many people know, all too often even after the testing phase is completed, the first months and sometimes years of service of new trains are plagued with unforeseen issues, so if there are known issues that haven't been resolved, you wouldn't dare let the units out into service and cause chaos.
Unlike a lot of cases, there is no TOC waiting for the 315s to be cascaded and extension of operation of 315s will only cause a problem if they are not all withdrawn by the time the tunnels open, which isn't for nearly 2 whole years yet. They have plenty of time, no reason to withdraw the management contract just because of late introduction of new trains - I imagine the ball is mostly in Bombardier's court, not MTR's.
Also, SFD means Salford Central, for Shenfield you mean SNF. Might seem pedantic, but if you're going to use those abbreviations, please at least get them right
