Tunnel entrance on the Oravita-Anina line.
This picture was taken from the rear of the train.
It can be noticed that the tunnel clerance is very small, enough though to allow coal wagons, that are most of the traffic on this line.
Some of the tunnels are not concrete or brick paved, but bored directly in the rock as it can be seen here.
