March 2026 Update

All track laid and feeder wires soldered to track. Onward to connecting feeders to the BUS wire . . . Then we continue to wire the turnouts to the Megapoints Controllers (MPC) circuit boards.

February 2026 Update

All the track for CB&Q 23rd St. shops and the Atlas turntable installed. Also the East Denver Belt Line trackage, UP Pulman Shops and the UP Wynkoop Street trackage.

I have installed the first of the Megapoints Controllers (MPC) circuit boards and have wired 9 of the Kato point (aka turnout) motors. These are activated by a pushbutton connected to the MPC board. Once wired up and tested I will install the DUT Control Panel which will make activating the pushbuttons easy and the installation of LED lights to indicate the direction of the points.

This photo shows, from left to right:

These photos show the MPC controller board display (left) and one of the MPC Kato control boards (right) on my laptop.

Early January 2026 update

Just got to tidy up the track to the CB&Q 23rd St Shops and turntable. Then onto BUS and turnout wiring.

Use of Kato turnouts together with Peco flex track has made track laying easier and faster.

The Joys of a Big Layout

My layout is really too large for me to seriously expect to get to an operational stage in under 5 years. Currently it is comprised of the following operational sections:

  1. South Denver and the Joint Line Loop
  2. Denver Union Terminal
  3. Denver North Yard
  4. The Flatirons
  5. Bond
  6. Craig Branch
  7. Coors Brewery Branch
  8. Grand Junction Return Loop

With the exception of Craig Branch and Coors Brewery Branch the track from North Yard to Grand Junction has been laid and the main line wired. The South Denver track has also been laid and wired.

Which brings me to the Denver Union Terminal section which incorporates the East Denver Belt Line, the UP Pulman Shops and the UP Wynkoop Street trackage. All of the passenger tracks to the actual station was laid by my friend Rod Taylor while the layout was in Townsville (QLD) in the years leading up to 2019. However the C&S inter-modal freight yard, the East Denver Belt Line and the UP trackage were still to be laid as of a couple of months ago.

In October 2025 I was seriously ill and spent about three weeks in bed. During that time I spent a lot of time thinking about what I wanted to achieve from my life and my layout. I remembered that my original goal was to duplicate the 1947 passenger timetable as published in the 1981 book by Forrest & Albi “Denver’s Railroads” after which my layout is named.

I consequently decided that I would finish laying the track around the Denver Union Terminal with a view to achieving my original goal. By coincidence I discovered a company called Megapoints Controllers who are British manufacturers of model railway layout control systems.

Megapoints Controllers supply PCB’s (Printed Circuit Boards) to control LEDs, cables and layout controls such as turnouts, turnout position, push buttons, block occupancy DCC accessories and route control. The boards will enable me to set up routes though Denver Union Terminal for the different passenger trains to conform with the 1947 timetable.

As of the time of writing this blog the only major section still to be laid is the UP Pulman Shops and the UP Wynkoop Street trackage. I have even installed the Atlas Turntable for the CB&Q 23rd St Shops.

So I will shortly be onto the BUS wiring together with the wiring required to install the Megapoints Controllers circuit boards.

Press: Restart!

It is 15+ months since my last Blog update but hopefully I am now back on track.

There were a number of reasons for my apparent lack of action, including:

  • My wife being confirmed as having Alzheimer’s disease as well as a number of other life threatening conditions with finally resulted in her heart stopping during a procedure in March this year.
  • A short in the trackwork exiting the 7 track Grand Jct. return loop. This was made more complicated than it should have been due to there being 7 tracks. If there had just been the one track troubleshooting would have been so much easier to find the fault.
  • Confusion with regard to the wiring of the 7 tracks. Which tracks had been wired and to which Power District.
  • Whilst road testing the return loop track looking for the sort it became clear that the trackwork was badly laid and needed relaying. Furthermore one half of the loop had been laid at too tight of a radius and needed extending by some 10 inches. A significant adjustment in N scale.

All and all the above just made it difficult to move forward. And when I did start to relay the 7 tracks it became apparent that the exercise was going to take a long time. Even now with all of the track laid, only one of the tracks is fully wired.

Work completed:

  • All 7 tracks that form the return loop have been laid and the alignment is much much better now that the minimum radius has been increased from 16½” to 22½” and the outside radius from 24″ to 31¼”.
  • The installation of a new control panel and Power District (PD zero) for just the return loop.
  • By redoing the return loop wiring the faulty block that had caused the short quickly became apparent and has now been fixed.

I can now run a locomotive non-stop around the whole layout (except though Denver Union Terminal trackage) without a problem recurring in the same place. In other words I still have track problems but not with the 7 track return loop. The next challenge is to run a 12 car freight train without a problem and then a 6 car passenger train pulled by a 4-6-6-4 Challenger steam locomotive.

At last — I have finished laying turnouts!

Progress since last update:

  • Finished laying all of the turnouts on the Denver Union Stockyards section.
  • Just got to realign the Kato track and turnouts in Commerce City.
  • Then on to Flatirons scenery and kit building.

Actioned since 14th January 2024:

  • North Yard Locomotive facilities — All turnouts laid.
  • Cargill, Alpine and RG Motorway Industries — All turnouts laid
  • Commerce City Industries — Kato turnouts and track partly laid
  • Denver Union Stockyards — Two of six turnouts laid

To be actioned in the immediate future:

  • Finish laying turnouts at Commerce City and Denver Stockyards
  • Ballast track between Big 10 Curve and Crescent Siding
  • Install Flatirons scenery
  • Start building kits

Action Plan

Due to the size and complexity of the new enlarged Coors Golden branch the sequence of track laying has been changed to the following:

  1. North Yard Locomotive facilities
  2. Cargill, Alpine and RG Motorway Industries
    • Scenery can now commence for modules 7 & 8 between Utah Jct. and the Moffatt Tunnel East Portal
  3. Commerce City Industries
  4. Denver Union Stockyards
    • Ballasting and applying of scenic material for the Denver yards & Denver stockyards together with finalising the wiring and the control panels can now commence
  5. Craig Branch
    • Scenery can now commence for module 11 between the West Portal and Craig
  6. Repair the Joint Line Return Loop & South Denver Module
    • Rewiring of the control panel will be required here
  7. Denver Union Station – C&S Trackage
  8. UP Industries & small yard
  9. Ford Motor & East Denver Belt Line Lead Tracks
    • Ballasting and applying of scenic material for the DUT, Rice yard & industries together with finalising the wiring and the control panels can now commence
  10. Coors Golden Branch

Finished laying the Main Line — at last!

Finally finished installing all 7 staging tracks (holding 14 18 car trains) at the Grand Jct. return loop which means that both the Rio Grande and CB&Q/UP main lines have been installed, leaving only the track for 9 branches and industry groupings to be laid.

Removed part of the scenery divider thereby making it possible to expand the Coors Brewery trackage by 150% whilst eliminating the Glenwood Springs Industrial area which was not prototype based.

Before:

After:

Coors Brewery now has 8 separate buildings:

  • Coors Brewery Main Building
  • Power Plant
  • Brewing & Transload Operations
  • Rocky Mountain Metal Container Factory
  • Coors Porcelain Company
  • Bottling Plant
  • Distribution Center
  • East Silos Elevator
