Couldn't they just push a suitably customised wagon through that lot?

And then find that where the ice was close or had formed around the
components of the overhead power lines attached to the tunnel roof you
have knocked them out of alighment or even dragged them down creating
really long delays while they get repaired.

Not a very practical suggestion.

So how do two blokes in orange anoraks deal with the issues you
imagine?



But carry on choosing between starting to Troll or not having any
common sense.

In the case of the Sussex tunnel there would be no overhead lines. It's
all third rail.

That as maybe but Jerk was commenting on the photo in the Ipswich Star
link of a Tunnel at Ipswich which does have overhead lines.

In the past I have seen photos of such wagons for use where they can
be used but cannot remember any UK example, in places where the
problem is frequent like some of the higher North American routes
routes they had them.

One of the UK canals had something similar for a canal tunnel but its
main use was for removing soot deposited by steam powered craft.
