Anyone know why there's an overhead wire on the southbound of highbury
station
(and maybe others, I didn't check) on the moorgate line? Its obviously not
some
old catenary since the line was always 3rd/4th rail and its only hung from
the
ceiling by some thin wires anyway. Is it in case a pan is left up at

Drayton?

I believe that's the case, yes; it's not powered, it's just to stop the
pan disassembing itself on the tunnel roof. I've a vague memory that it
was put in when the line was handed over to BR.


That seemed the most likely scenario to me. Wonder how often the pan gets
left up on that line? Must happen occasionally.

Is there nothing that will force a pan drop?

One Metro-North, for example, the M2 runs dual-mode DC on 3rd rail and
AC under the wire. I assume that the same happens with the newer M8.

As soon as that train's shoes come into contact with live 3rd rail, the
pantographs automatically come down. The train will not take power,


Thats a bit sophisticated for UK railways. Plus if it was done automatically
the RMT would probably call a strike about taking work away from its members,
thin end of the wedge, blah blah. I'm amazed we managed to get ATO anywhere
in this country.

Guess what? Drivers of ATO trains get paid more, or at least they did when
it was first introduced.

That doesn't surprise me. Another please-don't-strike bribe no doubt.

Also don't have door overrides in case of an overshoot.

You're not an MP are you? "Everyone gets a 0 or 1% pay rise except us."
