Despite the inherent inaccuracy in OO Gauge, it can indeed be made as a scale representation of real track. Put down the foreign HO, and use some real 4mm/ft scale track on your next project.

In this video I have a look at a few different track types, and build some Exactoscale FastTrack Concrete Sleeper Flat-Bottom Code 83, the track I will be using for my mainline scenes.

Recently I was invited to guest operate at Onehouse Model Railway. I brought some trains with me to give their legs a bit of a stretch. This particular train ran for a most of the day both pushing and pulling, and I'm very happy with how well it performed.

My Bachmann Class 25 would not run smoothly, and would not climb hills at all. In this video I dismantle it, diagnose the fault, repair the loco, and test my repair.

How to wire for block detection in DCC -- part 3.

I am extending my layout from the storage area up towards the main scenic layer. Part 1 covered basic physical installation, wiring and electronics. Part 2 covered basic software configuration using FLiMConfig and JMRI. In this third part I'm covering more advanced topics, with bi-directional sections configured for ABC braking in both directions, plus a DCC reversing section controlled from the route setting (not using any short detection).

How to wire for block detection in DCC -- part 2.

I am extending my layout from the storage area up towards the main scenic layer. Part 1 covered the physical installation, wiring and electronics. In this part I cover the software configuration using FLiMConfig and JMRI, and test the results.

How to wire for block detection in DCC.

I am extending my layout from the storage area up towards the main scenic layer. Two new block sections are being wired in. In part 1, I take you through how I wire for block detection in DCC. Part 2 will cover the computer configuration, and a demonstration of the new sections in action.

Let me know in the comments if you appreciate the voice-over.

A demonstration of trains queueing behind one another and moving ahead when the track is clear. This is achieved using ABC constant distance braking. Paths in and out of the storage yard are set by an NX panel.

Train detection is handled by MERG DTC-8s, layout control is by MERG CBUS hardware and JMRI on a PC, The ABC generators are custom built (five diodes and a relay). The relays are driven by MERG CANVOUT modules.

Timelapse of building a DCC ABC Braking generator for my Model Railway.

Work installing the DCC train detectors has progressed to the point the whole storage layer is now fully powered, so I can run a train around the storage layer for the first time.

Timelapse view of building a MERG DTC-8 train detector kit for my Model Railway.

Train detection for a model railway, using coils as transformers to detect current draw in block sections, with data feedback to JMRI.

The electronics are MERG kits -- the actual detector is a DTC-8, and CBus is used as the feedback bus.

The first signs of life from my Model Railway layout.

Points being successfully operated by servos, and the first train moving under it's own power.

Building the first phase of my Model Railway layout, started during lockdown.

This covers the lowest level with a storage yard and the start of the incline up to the next level.
