And now for something completely similar.

Seen this before?

click on image for a big juicy version…


This is another image of “Part 5”, the quad diamond in the centre of the Bronx Terminal yard, but slightly different.



The couplers always give it away….


N scale code 40 version of the quad diamond.





I initially drew the terminal in HO scale and when I finally decided to build it I opted for N scale. Looking closer at the project I had a bit of a change of heart, and decided to go back to the original plan in HO scale as I felt it just would not be possible to build this type of trackwork in N scale.

After building all the HO scale trackwork I felt that maybe there are some techniques that would allow an N scale version to be produced, and in code 40 to boot.

This weekend I was able to produce the quad diamond in N scale and it turned out very well. Now I have to decide if I am going to make the complete yard in N scale as well as in HO scale. I had planned on making the layout portable so I could take it to shows occasionally and building one in N scale would allow me to do that, and fit it into a suitcase….

I will post details on the techniques used to go from HO scale to N scale later this week.

After reviewing the post I realized the images look like the trackwork might have been scaled down in Photoshop. So I created a short video to prove this was really built, and not a Photoshop creation.

  1. Man, you ar really mad! I can’t stop admiring your work!

    In this densely packed intersecting trackwork, one could find some Italian spirit, if you like. Could it be the case that these Bronx yards had originally been built by some Italian immigrants?

    As I had noted in my comment on page 5, some similar arrangements of intersecting turnouts and curved crossings can be found in some turning pentacles in the Italian Alps, see

    But apart from that, I had some kind of déja vu when I first saw the general track plan of your yard.
    Now I finally remembered where I had seen some vaguely similar yard before. Guess where:
    Again in the Italian Alps, at Calalzo di Cadore in the Dolomiti:

  2. That’s very impressive! You are a masterbuilder! I have no words.
