Hello. As I wrote in previous message, ADe presentation'll be done during a Railway Fair here in Sardegna. So, this fair has been moved from 14 april to 27-28-29 april, and ADe presentation'll be done in those days too. But, while we wait to can see ADe in the fair, I'll show you something of her, in the meantime. So, in this video:
http://vimeo.com/39684183 you can see the mechanic tests and, as you can see, ADe is able to travel up to 12% gradients, coupled with two dummy railcars.
To make tests more hard, the mechanics components haven't been lubricated, and they are silent in this conditions too (noise in the video is higher than real, because videocamera amplifies automatically low noises when videos are done in a silent place).
Then, about Sardegna Railway Fair, I'll send you photos and videos, hoping you'll like it.
Best regards from Sardegna!
Stefano
