The equipment will be somewhat unique. I have found that there was an effort to standardize but there were also front line modifications and complete builds of cars.
There was a line of equipment manufactured in the UK a few years ago and I am slowly obtaining the items. The maker was Wrightlines and they are marked WW1 or War department. I have been slowly finding them to purchase by asking everyone I know if they have any. So if you have any spare kits please let me know as I have spare cash.
There was a large amount of lumber needed for the war and temporary saw mills were build just behind the lines. The mills looked much like they did in North America as they were built by Canadians deployed specifically to cut down wood.
This is a Wrightlines W023 kit I built but have not yet painted.
