SPENO US 6-1 is a ultra-sonic track test vehicle and was seen in Düsseldorf Hbf on 24th of May 2008.
If someone asks for the official road-number he will get different answers. If I understand it correct in Suomi it will be: 040 718 7414. The sticker from Infrabel is damaged, so I was unable to see if the agreement about registration has the no. A.0194.H or if it is the no. of the vehicle itself. SNCF registered the "Draisine US6-1" as 99 87 9 129 501-2, whereas in Germany it is 97-86 10 501 17-0... United Europe???
