I also thought it was Overhead wire maintenance but its powered from the overhead cable so its a live wire.

Maybe they measure the current draw as an efficiency barometer etc?

I am, sure someone will have the answer just now.

Again this vehicle has no number plates -see here

Did it look like a converted truck or a homebuilt rail trolley/powered vehicle? I cannot see the wheels properly but you may have noticed?

Gents,

It's is and overhead wire maintance vehicle!

Note that the technicians are actually in physical contact the overhead wire, which must be turned OFF and earthed before they start their duties!

The first picture is rather alarming, if you look rather carefully! There is just one "wood breaker" that protects the workers, from the adjoining line, with and electric unit at the head of the train!

The vehicle is powered by either by a 4 cylinder Cummings or Bell diesel engine!

If I'm correct, the panto on the overhead wire maintance vehicle, is used for testing the high of the contact wire, the tension on the contact wire, thickness and other vital contact dynamics, and it also checks that the dropper wire clips don't interfer with the contact between the panto's contact plate and contact wire!

I hope that helps
