I am going to start a new thread on this as we really have quite the mix of posts and cross posts covering a wide range of topics...maybe we can use this to talk specifics about the GP7...
The question came up about weather or not the GP7 will have smoke, it was reported on one of the S Guage Facebook groups, that a conversations was had with Ryan K from Lionel at the "big E meet" about this issue and he advised that due to space restrictions in the body that the electronics and the speaker would not allow for a smoke unit. There was no report on if the question about the tall trucks was asked. Also the Docksider will not have smoke for the same reason.
