Is your feature request related to a problem? Please describe.
I'm always frustrated when there's no way to distinguish between all-stop and express trains (without using route numbers), and 2 lines are bad.

Describe the solution you'd like
There are 2 Lines Between Express And All-Stop Trains, But I want to make it into one line.

Maybe the Hide Route option does what you're looking for? If you set the express route to hidden it should hide it from the system map.

On a completely unrelated topic, having that many tabs open ought to lag your computer?
