Bucuresti, Romania
The infrastructure was built by I.T.B. (now R.A.T.B.), using the same technologies used for tram lines at that moment, using wood and metal railway sleepers. The lines had 4 switches. They are were like the one in the pictures. This is a modified version of the swithces used at trams, with only one moving pin and manual mechanism that can be operated only by a crowbar.

More pictures & info about this line.
