That tends to be avoided due to problems getting paths down that way.Nowadays a convoluted trip to Stratford and around the loop there would probably be called for.
Sorry but this is fantasy; the answer is in the posts above.I suspect the traffic on the NLL would disallow this but if one was being creative you could always reverse the loco out then send it across the North London Incline, reverse at Camden Road then reverse again at Canonbury, with the loco ending up at Ferme Park, thence a reversal over the flyover and into the Cross.
Well... The track is there. Not sure about the signalling, especially at Canonbury?
I did say I was being creative, rather tongue in cheek, feel free to bin it if you feel so inclined.Sorry but this is fantasy; the answer is in the posts above.

You can't propel the support coach past more than one main aspect signal, so you'd have to turn the loco light engine. This means dragging the support coach out with the rest of the train. You'd also almost never find a path to reverse at Camden or Canonbury. Finally, because you've only got an engine on 1 end, you'd need to either run round at Ferme Park (not going to happen, it's chocca), attach a second diesel at ferme park or keep heading north, which would mean the loco will end up very far away from the coach carrying it's servicing crew.Bit uncalled for. They said it was creative and I see no technical reason you can't turn a loco a described unless there is restrictions on the loco or how far it can travel in "reverse".
Fair cop on your second point, but thanks for outlining why it wouldn't be possible anyway. Maybe I should have phrased it as a question...You can't propel the support coach past more than one main aspect signal, so you'd have to turn the loco light engine.

The original question asked how are locos turned, not how they might possibly be turned.
45mph running bunker first, in general. Varies between locos but anything running into King's Cross will be 45mph.I seem to recall there are also speed limitations running bunker first these days (20mph?)
Large express locos have full height full width tenders that are practically impossible to see round when going backward at any speed. Many smaller locos, especially BR standards, have some form of cab tender arrangement specially designed for working tender first and often with as good forward visability as when running chimney first.45mph running bunker first, in general.

Yep indeed, which is why tender-first is avoided wherever possible and tour programmes are planned very carefully to minimise it. There's also an issue with the tender wheels being fixed to the chassis and therefore unable to round corners or take S&C as effectively as locos with a leading pony truck. And a third point - running backwards is much less fuel efficient.Large express locos have full height full width tenders that are practically impossible to see round when going backward at any speed.
