AI enginesound

[johnnyboy99]

I've seen in some old MSTS videos that whenever an AI train was moving, rather than emitting the engine's own sounds, it would emit a fixed engine sound for AI locomotives (often it's the notch 4 sound from the default GP38 enginesound)

Is there a way to enable this in ORTS or did ORTS patch it out?
How does one switch from AI enginesounds to advanced AI enginesounds in MSTS?

How does one switch from AI enginesounds to advanced AI enginesounds in MSTS?

That's backwards, the advanced sounds are in Open Rails! --- and if you still wish to run AI sound msts style there are some sound files with specific AIEng.sms files that have sound sets as you describe.

Personally I have gotten rid of all the trailing, AI, etc. engine files --- so I can take advantage of jumping to any locomotive in the simulation and run it as the player train....all sounds, cabviews, & functions intact.

Gerry is correct. The "AI" (and "trailing") engine sounds were a relic of MSTS before MSTS Bin when only the player locomotive sounds would react to the locos' throttle settings. The AI files were speed controlled. OpenRails really doesn't need AI locomotive .eng files unless one wants to use "legacy" AI lighting settings in the .eng file. Most newer loco offerings include both "regular" and "AI" lighting settings in their .eng files. What I started doing years ago was to simply replace the .sms files in AI locomotives with "regular" .sms files from player-operable locomotives. Also, some content creators have started using the "AI" engine designation to identify a locomotive without a crew in the cab. Insofar as operation goes, those "AI" locomotives operate the same as a "regular" locomotive, there is just no crew in the cab. If I "remove" the crew from a loco cab (often it's just a freight animation), I will name the loco something like "ABCRR123-NC", the "NC" denoting No Crew.
