1981

Behind the scenes, engineers continued to develop the railcar apace. In 1981 they demonstrated the Class 628.1. The most important difference was that the second power car was dropped, because the remaining one was strong enough to move the coupled pair. The second unit could therefore be used as a driving car (designated the Class 928.1). Together with a few other changes, such as a simplified electrical system, the omission of one of the two toilets and one of the four entrances each side, and the installation of equipment to enable one-man operation, the new variant was even more economical. In addition there was a single-coach version again, the Class 627.1, of which 5 prototypes were procured. The new vehicles were tested for two years and, like their predecessors, proved to be outstanding, so that nothing stood in the way as the two-car version went into production. The single-unit variant did not, however, as it had only a few more seats than a bus and could not be deployed economically.

Coach number 628 102 is unusual in being the only one of this small batch with a 1st class compartment.
