I like European trains. I have MTH, ETS, and Merkur Euro trains, and I have bought a number of steam-era 1/43 die-cast cars and trucks so I can make my layout look more European when I'm running them.
I have three MTH Euro locomotives and matching trains - the French 241A steamer with the Orient Express, a Swiss Crocodile with 4-wheel boxcars and beer reefers, and a modern Swiss Cargo electric with a string of tank cars.
I also have a fairly extensive collection of ETS 3-rail trains, which come from the Czech Republic. These are tinplate and include some prototypes that you cannot find anywhere else, such as the Beyer-Garratt steam engines and the Seetal "baby" Swiss Crocodile. ETS makes a large assortment of nicely decorated beer cars and wine barrel cars, which are among my favorites.
