This really nice, extremely eye-catching and rare HO gauge rail bus combination by Marklin is either extremely rare or possible unique, its is based on the common 3016/4018 HO Schienenbus - Sammlerstück VT95 but is far more colourful! 

It is in excellent / mint condition, but does not come with its original box. 

The VT 95 was developed based on the experience gained with a number of prototypes and was delivered in 1952 by Waggonfabrik Uerdingen. 557 single-motored Class VT 95.9 units were built, as well as 564 Class VB 142 trailer cars and 60 two-wheeled railbus trailers for the transportation of luggage.

Its furnishings were very simple and resembled those in a bus (hence the name Schienenbus or railbus): one large open coach shared also by the engine driver, seats which can be folded two-ways depending on the direction of travel and simple lighting from bare light bulbs with no covers. 

15 VT 95 railbuses and 15 VB 142 trailer cars were delivered to the railways in Saarland in 1956. They were painted in DB red livery with the inscription SAAR. On the annexation of the Saarland into the Federal Republic of Germany these railbuses were taken over by the Bundesbahn.

In 1968 the vehicles were reclassified into Class 795 (power car) and Class 995 (trailer car).

This example is in excellent condition (see pictures). I have not tested it but see no reason why it would not run. 

This locomotive is really just very nice and high quality. 

This loco would look great 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.
