Video by Jack Zwick show the first Trolley with the onboard computer. I have added marker lights up front and 2 more led lights in the passenger area to the second version. I have also upgraded the battery to a lithium battery.

Autonomous G scale Hartline Motor Car uses magnets along the side of the track to stop and or reverse direction. The red marker lights oscillate back and forth when slowing and flash when at a stop. The car is powered by a Cordless Renovation 11.1 volt Lithium-ion battery and has these items installed in the car:

Quad Core Broadcom BCM2836 CPU with 1GB of RAM Raspberry pi computer, 3 relays, momentum unit, 11.1 volt lithium-ion battery, all lights have been replaced with LEDS, 2 1/2″  speaker, Phoenix P8 sound board, charge plug, and on/off/charge switch all install in the car. Installation including the Hartland Motor Car of your choice is $999.99.
