Around the Austro Hungarian Monarchy the HSR (Hungarian State Railways - also known as MÁV) made a fantastic engine. This was named as Model 424, but by its nickname it is also called "buffalo". This train is thought to be the most powerfull and most significant vehicle in the history of Hungary. Under the Kádár regime, these trains are multiplied, although the making of electrified trains also began to saw its heyday. Eventually in 1984 until 1986 steam trains were remowed from the MÁV. This model is a memento of that famous machine. It might be not as detailed and a perfect replica, to represent the power of this magnifiscent engine. Nevertheless if you want to enjoy the pure nostalgia and drive it, then I recommend downloading this schematic.

Enjoy :)
