Part 5

Quadruple diamond.


Click on image for better view….



The latest section in the project is the quad diamond at the centre of the yard. This is a bit of a showpiece and seems to be purposely placed to show off some engineers work. I won’t argue….





Here is the crossing in context at the end of the last piece.

  1. That track work is the best I have seen. Why do you model the track work in CAD? Do you use it to make a jig or are you building the track over a drawing? What CAD program are you using to model the track work?

  3. Hi Tim,

    Hey, I was looking at the map you posted earlier and couldn’t see any connection to adjacent railroads. How did cars enter and leave the Bronx Terminal?

  4. Tim, your work is really spectacular, Respect!!

    Coxy, maybe you should check Bronx Terminal section on Tim’s Port Kelsey site, there’s an article with pictures about it.


    Cars were transported via Harlem river on car floats.

  5. I like this type of trackwork, sratchbuilding is fun!!
    I’ve soldered quite a few turnouts. You did a good work.
    I’m eager to see the finished layout, with scenery.

  6. Hi Tim,

    Your work is absolutely marvellous, and your website too!
    Being a friend of absurd and complex trackwork myself, there is no other way than admiring it!
    A few ears ago, I built one of the most densely folded track situations I was aware in Europe at that time:
    A track pentacle (intersection of three turnouts and three curved diamonds) formerly used for turning locomotives in some Italian stations.
    At least one survives until today:
    See http://www.trenietram.it/venosta120205malles.htm for the prototype and
    http://www.mecschlanders.com/deutsch/Modellbahn/Seiten_Module_Vinschgerbahn/Bahnhof_Mals.htmfor my model.
    Of course my implementation is far from your sophistication, and after having seen your work, I’d almost like to start it over again…

    Regards, Moritz

  7. Oops, the link to my model is

    Sorry, Moritz

  8. Tim,
    Incredible work! What kind of soldering iron do you use for such fine joints? What sort of jigs do you use to put the rail together?

  9. Hi Tim, I know this is now 9 years on, but I was gob smacked when I first saw your track construction way back then. At the time I had just started making my own track and your layout and tremendous skill was a wonderful motivator for me to move into an area way outside my skill level at that time. It has always been there in the back of my mind, but little did I know I would be writing to you in 2018.

    I’m building a mid size layout in the UK and had designed a simple loco shed with pointwork I could easily manage. Unfortunately the design fell short in terms of access to the turntable, so a good friend who is the author of a superb track design software package called Templot came up with this in post 3437 of my layout thread in the RMweb website

    I’m now faced with 8 diamond crossings, a double slip and an outside slip in a relatively small area. Your website and the detailed instructions will now become my bible. I’ll give it my best shot, but this is way ahead of anything I have ever done.

    Thanks for the inspiration.
