I’ve made little visible progress in the last week or two. I’m waiting for the paint I ordered to come through, and in the meantime I’ve been looking for couplings that will work with my locos, and for modern 7mm figures.
The coupling problem is that I want to have link-and-pin couplings and automatic couplings working at the same time, which rules Kadee couplings out- they wouldn't fi t under that huge buffer. I’m hoping to build some transporter wagons one day and they will need to be coupled by a drawbar. In other words, I want to have the best of both worlds.
However, it seems I can get away with it. I’ve found that DG or B&B couplings will probably lurk unobtrusively under the buffers on G1, giving me the convenience of auto coupling and uncoupling, and still have prototypical coupling to drawbars.
I’ve also -with a lot of assistance from many different modellers- found a couple of sources for modern 7mm scale figures, which I was concerned about. One of them is actually quite close to where I live. Finally I’ve confirmed that the figures will be between 35 and 40mm tall which means my calculations for the doors (42mm, based on an assumption they would be a scale 6 feet) are correct. I’ve made the sides of the cab ready to fit. After painting...
