I don´t like the "small" LGB Diesel engines because they are out of scale: The Köf´s - especially KöF 6003 - are much too large; the Schöma is much to small. If it should represent the Furka Oberalp Tm 2/2 4971 or 4972 it must be two inches longer and almost one inch wider. The cabin is much too tiny. So I converted a worn-out 2060 to a Schöma Diesel Switcher with rear cabin like the "Klützer Kaffeebrenner".
Just to show how different Diesel engines can be (and what you can make out of the 2060) I´ll present the next photos:
