Last month myself and my partner travelled to London and was delayed for some time due to signal failure. We sat on the train for over an hour on the flatform with no announcement as to what was happening. After an hour we were told to try and get on another train that was due to set off (which we did) we didn't have allocated seats so had to sit apart also even though this train went straight into out final destination station (kingscross) we were told that we had to change trains at Doncaster and get on another train to London. Before getting to Doncaster the train then had mechanical issues so we waited for 45mins outside of Doncaster. Once we arrived into Doncaster station we got off the train as directed. We were then told on the platform that we could get back on the train and don't need to change (which we then did) then once back on the train we were told to get off (once again) as the train would not be leaving due to mechanical faults. We then got off the train (again) and onto another one that took us to London......2.5 hours late! We missed a close relatives entrance to their suprise birthday party and a friend (who we were sharing accommodation with) had to wait in kingscross for 2 hours due to our delay! Not happy to say the least! ????
