Horace, my layout is set in 1967 Western Region location is west country so I can allow for warships Both D600 (silverfox/lima) + D800 (All lima), baby warships (same as D600), hymeks (triang + Hornby), westerns (lima + 1 Hornby), blue pullmans (triang Hornby), lima class 117 +121s etc,
Mark 1 coaches there are plenty to choose from, I tend to use lima, and some Bachmann though, mixed blue/grey + maroon, with a small rake of mk2 (lima)
I did use to have triang mk1's, but the drag was stupid on them, so got rid of the lot and got lima + Bachmann, with the Bachmann ones I have replaced the narrow NEM couplings with the Hornby wide NEM couplings (with coupler) however the height difference on the couplers is noticeable though,
Loco wise, I've noticed the manufacturers dont really cater for this era much which annoys me
