[3] In 2002, car 2 was sent away for an overhaul, but the bankruptcy of the original contractor and the involvement of a replacement in an alleged bribery scandal meant that the overhaul was not completed and the car returned to the line until March 2019.

The overhaul included the replacement of the car floor, lighting, safety systems, electric drive, air conditioning and a new driver's seat.

AMT now plans to use the rebuilt car to double the service frequency to every 15 minutes.

It has a track gauge of 1,200 mm (3 ft 11+1⁄4 in), uses the Riggenbach rack system and is electrified at 550 V DC.

[1][2] The line serves 9 stops, including the two terminals, and currently operates an irregular timetable, with cars departing each terminus between every 30 and 40 minutes.
