Superior Detailing: All Kato Superliner cars and Material Handling Cars come with preinstalled detailing and thin railings. The passenger cars have complete upper and lower level interior detailing (which can be lit with the installation of an optional interior lighting kit 7-504), prototypical fluting on the exterior of the cars, and flush mounted and tinted windows. All cars have smooth rolling trucks with working bearing caps and shock absorber construction, and are weighted for a hefty feel and performance. The included Kinematic tight-lock couplers can be installed on both passenger and MHC's. Lighting Options: Both the Material Handling Cars and Passenger Cars have been designed for the easy installation of a marker light kit #958046. Simply remove a plate from the bottom of the car, insert the light board, and close it again to create a lighted marker light for the tail end of your Superliner consist.
