Drivers of streetcars for the Geneva public transport authority (TPG) are facing a quandary over their speed.

The TPG has come under fire for the slowness of its trams, now running on a recently expanded and rejigged network of routes.

But in the municipality of Meyrin, near Geneva’s airport, municipal police are complaining that the streetcars are travelling at excessive speeds.

The Tribune de Geneve reports that the municipal council, armed with detailed information obtained from police radars, has written to TPG management to complain of the speeding.

Of 69 trams checked, 45 were found to be travelling in excess of the limit of 30 kilometres an hour, according to the police records.

One was clocked at 48 km/h, while the average was 35 km/h.

“It is rather funny because in general we have difficulty travelling at the speed expected of us rather than the other way round,” a TPG spokesman told the Tribune de Genève.

Meyrin police say the tram drivers have responded to the concerns and are slowing down.

Difficult for critics, now, to complain if the streetcars are not as quick as they would like.
