Usage

This locomotive was introduced as a shunter by the manufacturer, Brush Traction. In Sri Lanka, these are mostly used in short passenger services. M7s are not permitted on the Main Line because of the low power and lack of dynamic braking but it can be run on all the other of the railway lines in Sri Lanka including the Kelani Valley Line.

gollark: I suppose they may get around this by not storing locations, but I'm not sure what they do and don't gather.
gollark: I figure that if you have a big set of locations plus pictures including other cars' license plates, that could allow tracking of cars.
gollark: Yes.
gollark: That seems kind of worrying.
gollark: True, true. I mostly avoid them because they're also pretty evil, but they're... a big company.
