Converting multiple parallel lines to 1 'average' line

Question

I have a railway dataset. I am wanting to do route analysis on it but it fails to solve most of the time, because often there are many lines on one route. Is there a way to simplify the above into 1 line that is the average position of the 4 lines in the pic above? Like below

Thanks

If the two lines are next to each other cannot you mark them as having different directions.

Typically parallel rails are different directions.

I found the Merge Divided Road tool and tried to use it, but it didnt really work - it went haywire with the big train yards with 10+ tracks next to each other. I will try and find a simplified dataset - I did have one originally but it was a bit TOO simplified
