DieselFuelLoco.gs - The 1st one is a script to make any diesel locomotive into a diesel fuel consuming locomotive. Currently the only documentation is in the comments in the script. However you should edit the top part of the script containing the constant definitions and set the bool value to enable or disable the fuel system on startup in surveyor and the horsepower defined constant based on the info contained in the script. The fuel rate "compression" value can be modified in the script and/or set in surveyor. Reference the script and class in the usual way in the loco's config file and place a copy of the script in the loco's directory.
