description
The vehicles stood out due to their 2,100 mm distance between the coupling axles. All locomotives had a Crampton type boiler, a round long boiler (that of the predecessor class VI had an oval cross-section) and an Allan trick control with a straight swing arm. The first machines had only one steam dome , the later had two. In the event of modifications, all vehicles received a new boiler and were then added to other series. The vehicles had type 3 T tenders . The last machines were taken out of service at the beginning of the 1920s.
