Hi George,
Of your list, only the Q1 4-6-4-4 came with TMCC (EOB system). The S1 6-4-4-6 and N1 2-10-2 (also the J1 2-10-4 and Q2 4-4-6-4) came with a QSI conventional reversing board and QSI sounds (think Proto-1). The I1 2-10-0 came with a QSI reversing board and no sound. The N2 2-10-2 has not been produced.
The Q1, I1 and N1 came with traction tires installed. The J1 as delivered had no tires but a replacement driver set with tires installed was in the box. If you wanted tires, you removed the original rear driver set and installed the replacement (pretty easy job). The S1 and Q2 came with no tires. You used to be able to contact 3rd Rail and they would sell you a Q2 rear driver set with tires installed, not sure about the S1.
If you care about smoke, only the Q1 has a fan driven smoke unit. All of the others have Seuthe units.
