There are 2 tunnels in the non eletiricfied section of msb,at least one of these tunnels has fall though map areas at both tunnel entrenes between the track and the tunnel opennings.I think it's the tunnel between stations.

Update...I hope this helps.the stations are on either side of this tunnel are ASCHUFFENBURG SUD/ASCHUFFENBURG HOCHSCHULE.This tunnel is in the area which branch lines off towards the track that has no overhead wires.
