SNCF Epoch 4/5, FS Epoch 3, Greek/Balkan railways, BR Modernisation Plan diesels. 1950s/60s American diesels. I model in HO scale these days, have also had a brief foray into O16.5/On30 and am dipping a cautious toe into French O Gauge, plus in an act of lunacy I've now acquired a French N Gauge layout.
