Linn,
Thanks for the update! Great photos!
The trucks are for combine #16 which is currently sitting truckless at the New Jersey Museum of Transportation. #16 is currently about 15 years, I believe, into a 100 year lease by the FEBT. Eventually the car body and the trucks will be re-united at Orbisonia.
There is also the actual EBT passenger truck which was used as a pattern for the new trucks. It will be re-assembled in working order and returned to the Tweetsie Railroad.It goes under their ex-EBT car.
