[GZG] Tanker Pods but wanders off in a wee world of its own

The Roam wheel widths are pretty much dependant on the width of a horse's bum
so we are stuck with that – so we get 4'8½" standard gauge, 5'3" Irish
standard gauge and the also slightly larger Russian and Iberian gauges. Though
even if the track seize is the same the loading gauge, sorry, it is the
kinematic envelope or some such, that is the killer and where Britain suffers
very badly as its loading gauge is much more restricted than the European
standard let alone the American one. An honourable exception being the former
GWR lines originally built to Brunel's (vastly superior but more expensive) 7'
broad gauge.

This is rather off topic but probably sufficiently interesting to pass on a
low traffic day. It might be useful as well – I am now wondering if they
would build railways on a colony world and what gauge they would be. I bought
some O gauge track and based it in 2' lengths on MDF shaped and ballasted to
look like a permanent way and I think it makes a wonderful addition to the
wargaming tabletop. I lucked onto a pile of Atlas American O gauge boxcar kits
very cheaply and these should eventually make their way onto the tabletop. A
railway stop would make a nice objective and I think there are photos of
French Char B1s caught on a train before they could be unloaded and a similar
scene in a novel with German or American AFVs caught on a train – possibly
'The Ten Thousand' by Harold Coyle (not Xenophon if there are AFVs – if they
had had them they would have gone to Persepolis – now there is an idea for
an alternative history story, drop a modern NATO force on exercise into the
past. Fun and games until the POL runs
out).

If we knew the scale of the GZG auxiliaries we could measure them and
calculate the approximate size of the pods. Not a great excuse to buy one
though but I think I will put one or two on my Christmas list.
