The Br643 is really cool, but I honestly like the Br644 a little bit more, since it's used on many routes. But I would also love to see the Br643
Marit Wesselink has already suggested this train in combination with the route Münster(Westf)Hbf - Enschede (NL). The combination would be lovely, especially because this route will shortly be upgraded for electric trains with new stations and the disappearing BR 643 on this route.
