Why do electric trains refuse to stay 2 right on one way (?)

[Leopold]

Why do electric trains on electrified track refuse to stay to the right on one way tracks? I have a game going where I've started with standard track that I've since thoroughly converted to electric (all track, depots and stations connected). I have one way signal patterns that expect trains to pass on the right. Older diesel trains follow the courses perfectly. Newly bought electric trains refuse to heed (obey) the one way signals but instead attempt to go the wrong way and then get stuck and stopped (back and forth behavior). Is it something to do with the side the electric lines actually exist on?

Whenever a vehicle is lost it will take random turns. Given it works for non-electric trains I think you're missing electrification somewhere on your track. This missing electrification makes it that the vehicle can't find a route to the destination and that is what makes it lost.

That's what I thought might be the problem so I did a thorough check with the electric tool broadly 'painting' (wide selection) over everything multiple times. I guess it's possible that some piece is still not electrified. I wish there was a tool that highlighted non-electric track (?)

Can you upload a savegame ?
