You may be forgiven for thinking that once the last service tram returns to depot at the end of each day that nothing will happen on a tramway until it all starts again the next day. But, of course, this is actually a short period where various maintenance and testing can take place. As was the case recently on Edinburgh Trams where one of their fleet of trams was fitted with specialist equipment.
The tram chosen was 254 – one of the rare trams which only has partial advertising instead of a full wrap – which was being used to check the overhead wires. As well as its pantograph it was also fitted with ultrasonic testing equipment to aid with this checking.
The specialist equipment was provided by a German company from near Berlin, Deutzer. They specialise in measurement services for transport companies and currently work with more than 100 companies in 25 countries worldwide.
