It may be that the extra two lines on the gauge were added sometime after 656 was built, perhaps after it finished service with the Danish State...
The dial of this particular gauge was re-made by specialists. They did a superb job of copying the original, except that the rather gay pink line...
Very nearly operating! Hydraulic exam passed and formal steam exam to come within the next few days, precisely 20 years since we started...
A noteworthy exception to Steve's excellent post: Danish 0-6-0T No. 656 at Nene Valley Railway has slide valves carrying a pressure relief...
Thanks yet again, Steve. Yes, I'm looking for problems -- to make sure they don't exist! It's the way I work. :) My engineering experience...
I'm faced with another problem with the brake blocks. This isn't connected with the flange profiles but I'll post it here as an extension of the...
I've been collecting information, drawings and documents on the class for 16 years, including a research visit to Denmark in 2005. However I'm...
Though the 'wearing' part of each block is similar, you may be able to see that the leading block has a bigger hole and more meat around it. It...
Good questions! The blocks on the driving and trailing wheelsets are mounted partway down hangers in an area with ample space. Those on the...
Many thanks for coming to my rescue again, Steve! The document and your comments together should be all I need, fingers crossed. I wasn't...
I'm preparing drawings of new brake blocks for the NVR's Danish 0-6-0T loco. These each have an extension that wraps over the tyre flange and...
That's very useful information about chilling, Steve. It reminds me (from 50 years ago!) that the camshaft lobes and rocker lever pads of our...
Thanks for your reply, Gary. I wonder if BR and/or IOW ever checked the tyre wear rate between different brake block compositions? Since asking...
