WHAT TYPE OF DIESEL ENGINES CAN I RUN ON BACHMANN TRACKS? DOES BACHMANN MAKE DIESEL ?

I'M NEW TO G SCALE, I LIKE THE IDEA OF RUNNING TRAINS OUTDOORS.
I BOUGHT THE BACHMANN STAINLESS STEEL TRACK FROM TRAINWORLD HERE ON LONG ISLAND. THE SALES PERSON SAID I COULD USE THEM OUT
DOORS. I HOPE HE WAS RIGHT BECAUSE I HAVE BEEN BUYING MORE OF THE SAME ON E-BAY.
