NO! NO! NO! traction tyres !!! why have they done this, Bachmann have never put them on ,even their 04 have none and can pull a house down . I thorught by making it with a metal bolier they had sorted it out. Having them on the model means the wheels with the traction tyres is a bigger diameter wheel ,and the older hornby one that had traction tyres used to shake like mad. i have two on order and now i think i will not get them.
