After a couple months of work, I finally finished working on my model of TORCO SD-35 number 7800. TORCO (Toledo Ore Railroad Company) was a C+O subsidiary that continued on to Chessie System and CSX. In 1982 three Chessie System SD-35's were sold to the subsidiary and renumber to 7800,7801, and 7802. The locomotives were remote controlled equipped for use at the ore dock in Toledo. The had 6 lights atop the cab. The lights were used to show various commands given. The model has these lights and they can be trigged with function 2 which makes the middle yellow set blink. The outer green lights come on with the front headlight, while the inner blue lights come on with the reverse light. Thanks for looking!
