Currently playing early start and trying to get my first industry set up.
Wanted to create a short line using an electric locomotive (modded)
Built an electric line with wooden sleepers and connected it to a power station and both the station, border, and shed.
I assemble my train and tell it go but it instead gives me an error saying first station not reachable.
I check to see if anything is disconnected everything seems fine.
The eye glass on the warning brings me to the entry port of the shed.

I went to construct a test build
(all vanilla items used in test)
2 depots/ 1 power station/ 2 Elines (1 wood/ 1 concrete)
I put a E-train into station 1 and tell it to move to station 2.
The E-train moves to station 2 but on the concrete line
I then delete the concrete line
I tell the E-train to go to station 1
Gives me the Error of "First stop is unreachable from vehicles current position"
I construct a concrete connection and tie it into the wooden segment and I get powered off signs on the track
I Try to send the loco again and I get the same message.
Further investigation I discovered that the tracks (wood E track) might not be receiving power thus not allowing Electric Trains to navigate on them.
