PlayStation Express Freight: Northampton - Edge Hill Spad

I've seen a few threads about this but none on the playstation forum.
I am stuck on Express Freight: Northampton - Edge Hill as I keep getting scenario failure signal passed at danger despite the fact there are no signals anywhere around.
I found one fix that said wait for 10 minutes at the first signal then go but while I was waiting it said I passed a signal at danger.
