The only pictures I have of a Patriotic "consist" were from a National Tracker Show we had in Fairfax a few years back. It is of MTH's fake American Freedom Train (MTH just took their generic passenger set and painted them in AFT colors). It is pulled by MTH's Freedom Train PA ABA set. The lead PA is a very good representation of the real FT PA. While not a model of a real consist, this train was a real crowd pleaser that got a lot of attention when it ran.
Sometimes I would pulled the cars with MTH's PRR scale GG1 in Bicentennial colors. This engine never existed because the Pennsy was long gone by the Centennial celebration, but like the cars it sure is good looking.
I tried to take the photos while the trains were running - bad idea. They all came out blurry. The next time I run them I'll take better pictures.
