CCG/Modelling: Tenders
Tenders Locomotives with tenders normally operate as a unit.
However, if you use the runaround command in Driver the locomotive leaves the tender behind. For steam tender config.txt files, add the following line:
tender 1
This ensures the tender stays with the locomotive.
Tenders Dump Coal
To prevent steam tenders or the coal bunker of a steamer being robbed at the Power station or any Multi industry track that is coal unload enabled, you should use the "No Dump" Script by Wulf_9, reproduced with permission.
You may find the scripts useful.
- Stop steam locos and tenders dumping coal.
This is a complete class - save to the filename and use as-is by copying all the text between the dotted lines
Tender version
// steamtender.gs // prevents unloading of coal at industries // ©Wulf_9, Sept `04 include "vehicle.gs" class Steam_Tender isclass Vehicle {
bool UnloadProduct(LoadingReport report) { bool UnloadFlag = false; return UnloadFlag; }
};
Include the script with the asset and add these lines to a tender config.txt file and it stops the tender dumping coal incorrectly.
Config.txt entries:-
script "steamtender" class "Steam_Tender"
A second script is available for tank engines.
Tank engine version
// steamtank.gs // prevents unloading of coal at industries // ©Wulf_9, Sept `04
include "vehicle.gs"
class Steam_Tank isclass Locomotive { bool UnloadProduct(LoadingReport report) { bool UnloadFlag = false; return UnloadFlag; } }; -------------------------------------------------------
The following lines should be included in the config.txt file
for the engine:
