Good to see things getting back to normal after the past couple of years. And even a bit of sunshine to boot! Looks like a good time being had by all, and quite a bit of time gone into building that track set up.

Good to see!

Interesting that your G1 / 16mm people seem to focus on Standard Gauge models. A lot of people in this aspect of model-engineering – including in my club (Weymouth) – apparently go for NG outline. Both choices are of equal merit, of course.

As far as I know all our members' locos in these scales are gas-fired.

Our equivalent carries its 32 and 45mm g. lines and steaming-bays on benching of very similar construction to yours; although its builders used large-diameter plastic drain-pipe for the columns, standing in concrete, fence-post style.

Be careful anyone else following suit: the brown PVC pipes as we used may not be ultra-violet resistant as they are intended for buried services. Realising this, we painted ours black to give them some weather protection.

We suffer from Geology. The ground is a very deep Oxford Clay deposit very susceptible to contracting and expanding according to water conditions. This affects the ground-level 5" and 7.25" line as well as the raised one; although fortunately not to the extent of replacement bus services… An eighth-scale Plasser & Theurer ballast-tamper, anyone? Though its movements have given the "garden-gauge" locos many gradients to tackle on lines that had all been built accurately level!

The rails are all linked electrically, to allow externally-powered electric locos, though I am not sure if this has happened. The electric models I have seen on it, carry their own batteries.

Fire-free BBQ…. Novel. I've visions of that being the opposite – all cold food straight from fridge and freezer! Or was it gas-fired?

Another club to which I belong decided against a barbeque last weekend partly on the possibility of rain that didn't happen; but anyway a BBQ even on our properly-built hearth would have been very risky, and also very undiplomatic, in a farming area during a drought. We had an indoor buffet instead.
