Building bridges

31 May

Quite a few of the collieries in Ayrshire had a combination of shallow adits and deeper shafts into the coal seams. We don’t have the space on Kirkmellington for the shallow adit itself but a bridge over the railway to it can be used and is a useful scenic break to hide the fiddle yard. This type of arrangement was common and the coal tubs would have been worked by hand or horse from the tunnel to the processing buildings.

Last night saw the construction of the base bridge deck. Plastruct truss section has been used as the main, outer girders with a smaller section trusses used internally as the spacers and diagonal bracing. Small H section plastic has the been used over this as the bearing structure for the track and wooden deck.

To ensure size and shaper were maintained, I used a plywood former, cut & marked to the required dimensions. The Plastruct was held to this by blu tac during assembly. After painting, the length of Peco N gauge track will be added along with the plywood strip decking. In the photos, these are just held on by blu tac for me to check fit etc. finally, handrails will be added and probably some brackets and cables / steam pipes.

The central support stanchion is a very old Hornby product used for their high level coal hopper but which looks the part. The abutment is SE Finecast brick styrene sheet on a thin plywood form.

Coal tubs and such will be developed later in the year.
