The Up & Down Great Rocks line loops back onto itself and passes under the passenger line near Chapel en le Frith.
Once your unlocked from Hindlow or Downlow you go down to the sidings just north of Buxton.
At that point you can do one of two things to go out short of going back up the hill.
Propel into Buxton station and use the left hand facing cross over the get access to the Down Main to Dove Holes and ultimately Hazel Grove (no its not a normal operation)
What with the length of the trains these days its not often we do that. especially considering the weight restrictions on the fore mentioned bridge. and that hill out of Buxton is long!
What we normally do is run around in the now extended sidings and go out over the Up & Down Great rocks line, it comes out of Buxton slowly turning left into Peak dale, on towards Chapel en le frith under the Down Main I could have taken from Buxton and on to Chinley.
It isnt common and when considering the amount of traffic wasnt ever common to get freight moves over the Up or Down Main. Arriving on the Up most common as you arrive light and the hills manageable.
The diesel depot at Buxton used to be very busy with refueling and light maintenance but that was in the days when we double and triple headed 37s to get the stone out, usually double, as the run around sidings didnt allow for trains over 21. I remember about 15-20 years ago we were given a rank that was to long for the sidings, they had to send a light loco to head the train back down to Great rocks jn.
Another time we come from Hindlow into the sidings, couldnt get the clearing point in the headshunt so we couldnt run around, there was enough room for the whole train in the sidings but now access to the run around road as the train was longer than the run around. So a light loco in the diesel depot was put into platform 2, we propelled into the platform, hooked up to the loco top n tail then back onto the sidings unhooked the lead loco and the whole train went down to Great rocks with the new loco.
That was because the train that went to Hindlow arrived over the Up Main, they didnt realise it was to long for the sidings and you can guess the rest.
Some right good days up in the high peak back then. Not been there in a long time now. but looking at RTT its not changed much apart from the new extended sidings which hjust allows longer trains but the moves look the same.
