Looking fine so far! This will be really impressive when both trestles will be complete!

It has been a really long time since my last update. Nothing new has been done. However there was recently a posting on the Whistle Post of a photo from Shorpy that is the very same coal yard I have been attempting to emulate with my large coal dealer trestle. Here it is.

This is the best photo I have found of the facility as of yet...

Nice job!

Very nice.
I have enjoyrd viewing your work and have gotten some ideas on building a shelf and supporting it on the wall.
I am looking forward to more of what you are accomplishing.

Looks like post WWII when the infrastructure use began to turn from railways to roads...

Prior to that is was plowing and sand or cinders. And back in the horse and buggy/cutter days, the snow was actually packed on the road so the runners would slide easier. I have read reports of the roads in Ottawa being several feet higher than the sidewalks and general "ground" level!

In my area, salt use has diminished over the last decade. If it often a mix of sand and salt that is used. All that salt was taking a serious toll on many infrastructures and bridge, and a environmental side-effect.
I toured buildings in downtown Montreal last week. It was quite impressive to see the extensive salt damage to buildings made of stone in urban context. Most of the degradation was quite recent due to increase in salt use. Even granite was decomposited by salt.
