I do not care what size the equipment is; my concern is with operability or how well the old will run on the new. The problem is every track switch has what is called a frog. This is a potential area for the wheel to go airy and derail, This is controlled by two things both of which are dependent on the scale and size of the wheels.
I don't think you need to worry about the future. Flyer wheels will still run on flyer compatible track and S scale wheels will run on scale track. Folks will just use whatever track works best to fulfill their goals for their layouts. If someone builds an S scale layout they are not going to care about running flyer equipment on it and if a guy likes flyer he will just buy the new cars in the flyer compatible wheel version. If someone can't decide between scale and flyer then he might have a problem but that's not gonna be something manufacturers need to worry about as the flyer compatible stuff and the scale stuff are so different that most modelers or operators only like one kind and don't want to mix them. As long as both types of wheels are available anyone that needs to can just change them and get rolling like we already routinely do with
SHS and American Models equipment. ...DaveBranum
