On the Lionel Pullmor Geeps, the engine is in the "front" of course because a Pullmor won't fit in the rear of the shell. One simple suggestion to try (other than adding another powered unit) is to run the Geep long hood forward, as many railroads did, which will put the motor and its weight on the rear truck. Also, the drive wheels on these Nickle Plate engines have magna-traction , so you might find its pulling power adequate. You can also try adding some weight (lead weights, for example) to the inside, which may give it even more traction.
