As suggested by "buffalo" in response to my last post I set up a bit of a jury rigged climb to test the locos. So I have jury rigged a piece of 4 foot long by 8 inch wide piece of ply, with a bit of a run-up...

The end is at just over 5 cm so that over 4 feet is just a bit steeper than the required slope!

First I put a completely straight track along the incline, and 4 four wheeled coaches as the train. The I tried in turn: U2 (0-6-2T), Mh6 (0-8-0), HF 110 (0-6-0), and ZB D11 (0-4-0).

All made it up the slope, although D11 (a tiny shunter) did slip a bit. All of them managed a stop part way up the hill.

Next I replaced the straights with sequence of curves to simulate a track snaking up the hill. The results with the same rake were encouraging but not as good:

• U2 - Managed the slope well (with minor slippage)
  
• Mh6 - Incline? What Incline?
  
• HF110 - I think I can, but only with three coaches!
  
• D11 - Sorry, I'm not built for this!
  

The performance of the U2 was a surprise, I really did not expect it to do so well.

Lastly I decided to put a rake of 4 Mariazeller coaches on the windy slope, this is an old 4 coach Liliput set I got from the German Railway Society years ago and not something I've seen since!

To test these coaches on the incline, I tried two locos: Mh.6 and an old Liliput 2095 loco. Both of these didn't even know the slope was there.

The bogie coaches do look rather entertaining on the windy slope:

Anyway, I think possibly with fiddling (i.e. improving the bearings on the coaches) both the D11 and the HF 110's should be able to get up the slope with a rake of 4 (remember this was a bit steeper than required). So all good!
