History of the DAB 15-1200C

A Danish answer to the low-floor city bus

The 15-1200C was developed as DAB’s series 15 and presented in 1992, the year the first buses were built. Its low floor was a step away from the high-floor city buses DAB had built since the 1960s, when the company supplied Copenhagen with a standardised bus in seven distinct models with aluminium bodies of modular construction. The new model kept the aluminium structure but lowered the floor to 320 mm at the front overhang and 340 mm at the rear, with doors in a 2-2-2 layout and large round windows.

Engineering

The bus relied on fully automatic gearboxes: ZF 4HP500 and 5HP500 units or the Voith D851.2. The engine was the DAF RS200L until 1996, when the DAF GS200M took over; a MAN D0826 LUH12 of 162 kW (220 hp) was also available, while the DAF units produced 200 kW (272 hp). Braking assistance was limited to ABS, without the traction and stability systems that became common later.

In Denmark

DAB had worked with Leyland since 1953 and was majority-owned by Leyland from the 1970s, when the factory was renamed Leyland-DAB; after Leyland’s collapse the DAB division passed to Volvo with the sale of Leyland Bus, and in 1990 DAB joined the United Bus group with DAF Bus, Bova, Den Oudsten and Optare. The United Bus venture failed and DAB became a wholly Danish company again. Some Danish operators also ran the 15-1200C on LPG, with the gas tank mounted on the roof.

A second life in Poland

In the mid-1990s the model reached Poland through MZK Koszalin, which bought a single bus with fleet number 1139 after it had served in Denmark as a demonstration vehicle; a second, 1194, arrived a few years later. Buses of the type also worked in Gliwice and Głogów, where the local operator KM Głogów ran examples of the model. Surviving vehicles photographed in Poland were built between 1993 and 1996.

The end of the DAB name

Scania took over the Silkeborg factory in 1995 and introduced its own OmniCity family, but production of the 15-1200C continued until 1999, when DAB’s own models were dropped. The factory was renamed Scania A/B, Silkeborg in 1997 and was sold in 2002 to the Norwegian bodybuilder Vest Busscar, which ended the DAB name after ninety years.
