Yes Russ, it was quite common on early steam engines in continental Europ.
Although our 0-8-0 was built in 1918, her design was from the end of 19th century. The Germans started studying their 60cm gauge fields railway system as early as the 1880's. In 1890 they bought 76 "double engines" called "Zwilling". In fact it was two identical (execpt in their cab height) coupled back to back.
In 1905 they began build the more powerfull 0-8-0 "
Brigadelokomotiven" type, also called
DFB (Deutsch Feld Bahn) by railfans.
This one is at Frankfurter FeldBahn Museum.
Their 2 trucks tender increased their autonomy, but was mainly for water because the cab rear panel was plain. BTW, it also carried coal, but you needed to shovel it to refill the loco's coal bunker.
Construction continued until the beginning of WWI, and during the war. It was the most numerous narrow gauge series ever built, with a total of 2524 engines built !!!
In fact, a huge number of engines began a new civil life after the war in Europe and almost every were in the world.
In Europe, almost every 60cm gauge tourist railway has one of this 0-8-0, and most firemen and engineers have run one.
