Bachmann trains, Chattanoga & Empire Builder

[cvn1932]

I have two HO Bachmann trains, the Chattanoga and Empire Builder.
I found out that the ez track curves for the Chattanoga layout are different than the Empire Builder.
I was trying my Empire Builder on the ez track used for the Chattanoga and the passenger cars kept jumping the track on the curves and did not realize the curved track is different for each train.
Would it be possible to make a note on the instructions for the train that the curved track is strickly for this train and not to use for any other Bachmann HO train.
Sincerely, C.V.(Bud)Norris
