Sorry.Sounds as though it might refer to a grade separated junction.
Nope.High speed points maybe (although I think the answer by @RDP is more likely)?
Not that either I'm afraid.A swing nose crossing?
A bit closer but still incorrect I'm afraidThe only other thing I can think of is hump shunting.
A bit warmer but not hot enough.Fly shunting?
Correct. Please slip us the next question.Slip coach?
White but repainted black to make them less visible in the wartime blackout?What colour did the LNER paint the first overhead structures on the Woodhead line, and why were they repainted in a different colour very shortly after?
On the right lines on the second point, but not quite... and no, they weren't originally painted white.White but repainted black to make them less visible in the wartime blackout?
Nope! ☺️Black to grey? Grey being less visible against the skyline
No, @Spamcan81 was closer.Is the reason the establishment of the national park?
No - but if you think about rust protection it might help.Unpainted rusty steel to grey?
I'll give you that one! They were painted red oxide (a browny-red) but when war broke out, it was quickly realised that they created a lovely red trail leading enemy planes down Longdendale towards Manchester, so they were hurriedly painted a dull grey.Red Oxide paint,then repainted to avoid confusion?
