If you would like some Austrian class 2091 haulage on the narrow-gauge Döllnitzbahn in the former East Germany, best get your skates on.
They have acquired more modern ÖBB diesel traction in the form of 760mm diesel railcar 5090 015. This is currently going through works at Ostritz, however will emerge as “137 515” and will be put to work on the diesel turns on the Döllnitzbahn with a trailer vehicle from Summer 2018.
Currently the regular diesel workings on this pleasant line, situated roughly midway between Leipzig and Dresden, and which connects into and out of the main line at Oschatz, are in the hands of two pre-war centre-cab 1-Bo-1 Austrian diesel-electric locos. 199 030 (ex-ÖBB 2091 010) and 199 031 (ex-ÖBB 2091 012) are two of the nine extant members of a once twelve-strong class, built between 1936 and 1938.
Currently, 199 030 is away for repairs to collision damage sustained on 6th November 2017 when it struck a badly parked lorry (link to news article here); consequently 199 031 is quite busy at the moment!

The Döllnitzbahn enjoys a daily service, with one loco and set of stock in use each day. There are occasional days when the 2091s get a rest and a steam loco comes out to play instead, but these are clearly advertised, so planning a trip to take in the diesel traction is not difficult. Timetable detail for 2018 can be found here.
The two 2091s are intended to be kept in reserve, however if you want to sample them in service, you really need to make plans to visit before the DMU arrives.
