Yesterday (26th November) I was in London, arrived at London Euston for film the 5th Railtour of the day!! 34067 Tangmere was due to arrive on Platform 18, waited for the steam Locomotive to arrive, loads of people there all ready to film the Southern Locomotive into the Platform, an few minutes before it arrive they put an announcement out saying that Passengers waiting for the charter train are advised that its NOT Arriving onto Platform 18, you are advised to head back to the main concourse and check the departure boards. So now wondering what Platform 34067 was due to arrive, everyone headed back to the main concourse, when i got there i check the arrival boards and had no Platform allocation, next second it got changed back to Platform 18!! Started walking back towards Platform 18, an couple of people who were also waiting to film and take photos of 34067 saw us heading back and they said to us that it's not arriving on Platform 18, we told then it is becuase they put it back on 18, got to the top of the ramp at Euston and 34067 arrived!!!!! There was an lot of unhappy people that were annoyed from what happened, i evenn spoke to a few on duty members of Virrgin Train Staff who were there to take photos and videos and they were happy as well and they were going to give Network Rail a good telling off Me personally thinks that Network Rail did that on purpose and i felt disgusted by their actions, they messed an lot of people around and also personally thinks that it wasn''t fair on a lot of people!
