Not if the GSM-R equipment does NOT have its own internal battery. Multiple units are not typically fitted with GSM-R with internal batteries, they rely on the train batteries. If the collision damage has put +ve battery voltage carrying cables to negative or vehicle body then breakers will...

And that 1% reduction in revenue for the single quarter more than wipes out the operational savings which led to an 11% reduction in operating subsidies for the previous 12 months....

GSM-R is powered from the train batteries as a back up in the event of a loss of traction power but I would presume that the damage to both trains was so significant that battery power was lost (short circuits in cabling etc.).

Bingo! McCooeys and Dunchers are residents of Belfast and HMS Belfast's "A" & "B" turrets are trained such that if they were fired the shells would land on London gateway Services. Over to you, me old salty sea dog!

A ship, technically, but yes.

Double post

They are indeed, also known as London Gateway Services, but the answer is not types of wood. You've got one part of the cryptic decoding done....

Nope.

Why do you need to be careful about what you say about McCooeys or Dunchers when you stop for a coffee at the first services on the M1 having left London?

Based on my memory of the books it'll be "Ipcress File", "Billion Dollar Brain", "Funeral in Berlin" and possibly "Horse under water"

Exactly. The required track geometry has been lost because of settlement of the soil under the ballast. There wasn't enough existing ballast under the track to allow the tamper to lift the track back into position and be able to pack the voids from the lift. So new ballast is dumped on top of...

That's not really how tamping works. Tamping is a consequence of adjusting the track geometry. The tamper picks up the rail with lifting clamps and lifts and slews the track into the correct position. The tines are then inserted into the ballast while the tamper is still lifting the track and...

Indeed. With shunter/drivers who will swear back is white and that they definitely checked the blades were thrown and latched in place despite the forward facing CCTV from the train clearly showing they weren't even looking at the points when they threw the handle and you could see the blades...

We had our own re-railing gang with a variety of jacks and traversing tables and air bags and generator sets and all the blocks of wood etc. But a lot of the time you could, because they were invariably low speed and only one or two axles "in the dirt", with judicious use lumps of wood simply...
