This very nice HO gauge locomotive by Roco is 62815 a DR Class V100 diesel locomotive in red livery, it has running number 110 123-7.

The DR Class V 100, redesignated the Class 110 in 1970, was a four-axled diesel locomotive for medium duties operated by the Deutsche Reichsbahn of East Germany. Locomotives of the type were also supplied to railways in China and Czechoslovakia and to various industrial operators. In all, 1,145 units of this class were built from 1964. 

After the merger of the West and East German railways to create Deutsche Bahn AG, the large fleet of this very robust and reliable East German locomotive was no longer wanted on German rails. An unusual problem arose with a rolling motion that was traced to the wheel profile. On newly laid and ground rails the engine rocked at high speeds. The Deutsche Bahn finally reduced its permitted maximum speed to 80 km/h (50 mph), which meant it could be taken out of service because this speed was too low for duties on main lines. Individual locomotives were later equipped with special shock absorbers on their bogies to counter the rocking motion.

The loco is in excellent condition as you can see in the pictures, I have not tested it but I can see no reason why it would not run, so it it is sold in untested condition, but a complete external visual inspection has shown no reason why this loco would not run and it the overall condition is very good. It comes complete with its box. The box is in good condition.

Overall this is a really nice scale locomotive and would look fantastic on a layout.

Do please have a look at my other listings, I typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items.

Note: I do recommend all locos are cleaned & serviced, as they have some age to them even if the quality looks at the highest level (fairly standard advice for all locos!).
