Stanway Line 2 (now officially called Tempo 2, or T2 for short) is the main north-south bus line of Nancy. It was inaugurated in the summer of 2013 and was advertised as being a special kind of bus line called BHNS for bus à haut niveau de service (bus with a high level of service).
Originally this was meant to be a guided trolleybus line, like line 1, but after more than a decade of experience both the local transit authority and the manufacturer Bombardier had come to the conclusion that guided trolleybuses are too expensive and unreliable, so the new north-south line became a bus line instead. The new buses were made to look very similar to the guided trolleybuses, and they also run every five minutes during the rush hours (every ten minutes otherwise). They are powered by natural gas to reduce air pollution.
I took line 2 from the city center to Jarville-la-Malgrange, and later back from the southern terminus in Laneuveville-devant-Nancy. My impression is that it is a perfectly serviceable and efficient bus line, but I wouldn’t say it is so innovative that it deserves a special set of initials.
