sd40 7171 problem in ORTS

[johnnyboy99]

I installed ORTS recently and it appears the default AI SD40 has a big bounding box, resulting in there being a big empty space at both ends of the locomotive when coupled to a train. Is there a way to fix this?

Try this: Bounding Box Editor

I have BBoxVer1.3 but can't locate in the library.

In OR the bounding box isn't suppose to be used, so the problem maybe in the engine size measurements.

The problem is the following line in the sd40.eng file:

   Size ( 10ft 15ft+10in 65ft+1m )

Open Rails does not like the mixed units in the last number. Since InertiaTensor is defined the same (except the "+1m"), I just removed the "+1m".

That made the gaps go away.

BTW, there is a warning logged in the OpenRails.log file:

Warning: Found a suffix 'ft+1m' which could not be parsed as a Distance unit in C:\Games\OpenRails\Open Rails Content\PrevMSTS\trains\trainset\SD40\sd40.eng:line 7

Also you might like to update to a working engine with a cabivew that fixes that issue. This is the model I use:

Numerous better models out there and some are struggling with T/A originals. Good grief.
