Took measurements of all larger scale engines for distance between lead truck front axle and rear bogey axle for required length of TT bridge track.  Thought about this, decided to list for others to have for their info in quest for correct TT for current or future motive power units.  Hope this is of use to others and save time/money when matching TT bridge and wheel arrangements.

The TT bridge track measures a tight 28in, so it is good for most motive power.  Half of my larger engines fit this, only need to add 2.5in on each end and all steam power fits on TT bridge.  There are "prototypical" examples of this for upgraded TT  to handle larger steam by many railroads.  On some, the additional rail lengths were attached as needed and then elevated to clear the whisker tracks until aligned.
