Hi,

Thought I would post some images of my latest piece of trackwork build in N scale.

This is a quad diamond, part of the Bronx Terminal that once existed in New York. I have been building this in HO scale, but thought I would take a crack at on in N scale as well.

More on this can be found on my CNJ Bronx Terminal website.

Tim, the craftsmanship of your trackwork has always impressed me! Very, very nice work!

The quad crossing looks great. I built one for the UPRR Rochelle Sub a number of year ago and was never really very happy with it. As I am rebuilding Rochelle as part of the new UPRR Geneva Sub, I am looking forward to doing a much better job on the quad crossing. One thing that was difficult was the electrical aspect of the crossing. Do you have detailed information on where gaps are cut in the PC ties and how the quad crossing is wired?

How do you file the rail to the precise angles needed? The PointForm makes great frogs, but obviously only one angle. I can't see how to "freehand" the angle with the degree of precision necessary for good joints.

Hi Daryl,

All the gaps will be cut with a jewelers saw prior to installing the trackwork in place. Once in place cutting a gap in such small and complex track with any type of rotary tool would likely be impossible.

I suspect I will find out though, surly one will be missed....

They can be hard to find, but there are really thin diamond dremel wheels that go through track like butter. They are like $12 per wheel, but last a lot longer than the normal abrasive discs. They cut a thinner notch too.

Indeed the thin diamond wheels are excellent. However, they are not the panacea for all circumstances. With tight clearances and especially with N and smaller scales, it's not the thinness, but the diameter and it's associated 'collateral' damage of extending out beyond the cutting area of those close quarters.

What we really need is a supper thin reciprocal saw arrangement that can be easily controlled. An affordable laser cutter would also be rather nice tool to consider.
