Okay, now I am back from my holiday I went back to work last night and was told by my team leader that there are blocks on all 4 lines at Shenfield for the next 8 weekends for Crossrail work. Unfortunately, this does cover a few of our games.
The Chelsea cup game is a week day as you probably know, so the Abellio line should be fine for that.
By the time the Arsenal game comes around, it will be close to Christmas so I imagine there will be more blocks and more trouble getting to the home games.
Sorry that I have to tell you the bad news! The C2C line as far as I’m aware will be running up and fine.
