Thank you for your help. So on the 1996 TT if the Nordhausen train is a through train would it arrive chimney first? With only the Brocken train arriving bunker first or would there be a swap? The timetabling looks heavy in the afternoon just after one, then again around two, and then after three. This always seems to coincide with an arrival from Nordhausen, so I wondered if this was the loco swap that gets mentioned. Thanks again for your help, the timetabling and swaps sound fascinating. Thanks again.The Nordhausen Train is an interesting conundrum.
Certainly the loco way round will be a clue to where it is going. Arriving x Nordhausen bunker first and it will go up the Broken. Chimney first and it will go through to Wernigerode.
Some timetables it has gone through to Wernigerode others it turns round at DAH and goes to the Broken. The Timetable itself will be the clue of this. For instance the current TT in line shows 8920 x Nordhausen to Btokenthus the coaches will go through. Return is 8929 again shown as a through train. Look at the columns for the destination/from note. It has I think been a few years since the coaches have gone through to Wernigerode rather than turning round at DAH to go up the Broken, perhaps the HSB has git their customer care into gear!
EDIT I visited the Harz in 1996 so have a Timetable that you could be looking at. During the Summer period and indeed the Spring of 97 there were 3 through trains from Nordhausen to Wernigerode and the one to the Broken. Similar in return. There was also a curious Railcar the ran from Nordhausen to DAH and return, look at 8930/8929. Hope this helps some.
