Data from "kKBSt 3.0" in Wikipedia at [], last accessed 27 November 2025. Works number was 268 in 1879.
A photograph of this diminutive tank locomotive reveals all about its mission. Its front half contained the short boiler, tall stack, big steam dome, and abbreviated cab. The rear half of this reproduced a baggage-car (Gepäckraum) accessed through sliding doors within an short, enclosed, windowless body. Under the running board, cylinders mounted behind the small drivers drove the leading axle while a trailing axle of the same diameter carried the Gepäckraum.
In other words, take away the chimney and dome, and the 401 looks like a local-delivery of significantly later vintage driven by an internal-combustion-engine on Austrian roads. Like the truck, the 401 could be operated by one crew member.
Chief inspector Anton Elbel designed the 401 to operate lightly used branch lines. The 401 could carry up to 20 passengers in a trailing coach. Even when carrying just the passengers, the train made money. When the ONWB joined the kkStB, the 401 became kkStB 3.001.
As the kkStB decommissioned several other baggage engines, it sent the 001 to the Austrian Railway Museum. In 1920, however, the museum's acquisition of a rack railway locomotive led to the 001 removal and scrapping.
Along with several other baggage locomotives, the 001
