I am now the proud owner of 3 APA boxes. I have knocked one up quickly, and a couple of issues have arisen:

1. The 150mm radius Curves fit, but only just. I can carry on with them, but it will be tight. Alternatively I can utilise 140mm Curves from Tomix, however the corresponding points are Tomix too, and I can't seem to find out if they are compatible with Kato Switches.

2. The upright posts are a little wider than expected, but this can be got round with a couple of gentle S Bends and some surgery to them.

I say construction is about to begin as I may completely scrap the APA boxes and go for some bespoke laser cut baseboards, which would give me a lot more to play with.

This gives me the chance to use the Kibri Albula Viaduct, and add some more buildings into the layout. The APA boxes wouldn't go wont waste as a near 2 year old in the house can use them for their original purpose.

Why does this hobby constantly through decisions at us?
