Hi,
There is no "right" answer, prototypes vary. Also the location and type of traffic has an important bearing on the timbering layout -- is this in a fast running line, or the gas works sidings?
For a fast running line the timbering layout would be drawn up in the company's p.w. design office. For yards and sidings it would likely be made up on site by the p.w. gang, often making use of serviceable used materials.
A couple of details:
1. the mark in Templot is not a tie-bar. Prototype stretcher bars don't extend beyond the timber ends, and are connected to the drive rodding, which can be at either end (but not both). The mark in Templot is purely a template construction symbol called the "drive slot" to indicate the position of the slot in the baseboard for the point motor linkage. The mark is extended on one side as an aid to identifying the hand of the switch.
2. the special switch chairs must fit the rails in the designed locations, so the switch timbers can't be moved from their design positions. But ordinary chairs can be moved along as needed, provided the rail is supported at not more than about 31" centres.
I suggest your plan might be timbered something like this:
The switch timbers at A have been shortened to clear the conflicting sleepers.
The switch timbers at B have been extended to replace the conflicting sleepers.
The sleepers at C have been shoved along a little for better spacing.
The timbering style in the turnout has been changed to equalized (skewed) because this always makes it easier to adjust timbering layouts.
The above changes are made using the
shove timbers functions. This screenshot also shows some of the experimental work I am doing on the chairing for 3D printing.
cheers,
Martin.
