Because only one train at a time can run between Ormskirk and Preston and between Kirkham & Wesham and Blackpool South due to those lines being single, so they have limited capacity.
Been playing this tonight. I can't wait for the electrics to be added to this route as AI (and hopefully some loco swaps as well). The route really feels weird without the 86 and 87 at Preston. I know JT said they hadn't started on this, but they need to!
The should slightly change that. I was driving a free roam Hst to Blackpool south and found another train was blocking me at a red signal on the single track. If it waits at the previous signal I can pass it.
