the Reading work is a huge project in its own righ to reduce conflicts, increase paths, improve interchabnge facilities and maintain 'normal service' on all lines throughout the cionstruction period. If Crossrail is extended to reading, it could further complicate matters, though AIUI NR have 'futureproofed' the new Reading layout for Crossrail, and Airlink.
I used to travel from Reading to Paddington daily, a lot of the problems of conjestion were caused by trains always leaving Paddington late, and in close succession, then all arriving within minutes at Reading, e.g. there used to be (can't remember the exact timings but something like this) an 18:00 leaving paddington, then an 18:05 then 18:15 I think. They would all be lined up in paddington, and it would always be a good game to predict which train would actually leave first and jump on it, the 18:00 or 18:05, and it was often the 18:05! They would both leave late, within minutes of eachother, and arrive at Reading at almost the same time, instead of 5 minutes apprt. It was imcompetence at a high level!
I still don't see why they need extra platforms (are they still building more???), can someone explain it to me please?
They have enough bays, and enough through platforms. Reading only has very aproximatly 296 stopping trains a day, Vauxhall for example has around 750, with fewer platforms. Is the real problem not that almost every FGW train that arrives at Reading is either arriving when its meant to depart, or a minute or so after (and is still counted as being ontime for stats purposes), then it takes longer to get the train to depart as they HSTs dont have electric doors, so more delays, at which point the next train is waiting outside.....
