Abstract: The present invention include a non-motorized low-profile platform cart system for transporting heavy equipment, machinery and vehicles to limited access areas. The system includes a low profile platform cart without motorization and a portable loading ramp for loading vehicles and such onto the cart. The cart may be moved by any motor power source with hi-rail capability other than train engines. The cart also has a rear plow which is capable of removing ballast and debris from the tracks. Use of the cart and ramp allow easy access to limited access areas such as construction areas and bridge repair areas, as well as limited access railway areas where there are no access roads. This invention produces a simple, highly economical solution to the problem of limited access.
