I wanted to show my working (as my Math teacher always encouraged me to do) on the layout design as it evolves to meet my needs. I was not happy with the way the original design performed when I looked at the yard throat design. There was an ‘irksome’ separation between the mainline and the branchline running into the future Industrial park extension. Image 1 below, shows my attempt to fix that issue; a simplified version of the first track layout.
The throat area is the set of switches around the Interchange track and the branch out to the rest of the industrial park. In mock operating sessions the biggest issue I had on the fist design was the lead out to the rest of the industrial park had crept down quite a way onto the upright of the L shaped boards. Keep in mind here that the other boards are not yet attached to the three boards in the image.
Additionally, I wanted to have a better yard throat, that was easier to switch through and took up less space. After due reflection, the layout just didn’t look right for a small, smart industrial line with the smarts to build their own industrial park out of a couple of abandoned branch lines. Thus we arrive at version 3.
First there’s a better use of space,and visual appeal (to me anyway) with the long classification track #1, and the maintenance lead / class track # 2 being at the front end of the board.
All of it coming direct off the old main (now the interchange track). It simply feels better, and right in a way that the previous versions did not. I’ve run a quick thought exercise ops session on the new layout, and it also makes it easier to do business on the new layout. I’ll post the results of that a few days in the future once I have some other modelling work that I have to complete done.
On reflection I will be moving the switch (currently a Wye that will be replaced with a left #5) further back toward the camera to extend the run-around on both the main and the loop. This will stop just short of the road overpass and ensure that a loco can pull clear of the switch to allow the run-around move to take place. Additionally it will allow the
That’s it for me at the moment. Talk to you all later. If you have any questions let me know.
