    AI and Trail.eng Files

    Hi all,

    I've been away for many years and have just rediscovered MSTS. I've noticed that some developers are adding "AI.eng" and "trail.eng" files to locomotive folders and would like to know what lines I would need to modify to a player .eng file to make it either AI or trailing .eng? Somehow I'm guessing there's more to it than removing the cabview and headout entries.

    Thanks in advance,

    Bill

    This is what I do:For trail engines,no head or ditchlights;no cabview;no engine controls.For AI engines,as for trail except they need AI head and ditchlights and the warning beacon ( for engines without ditchlights ).You can keep truck and step lights if they are there already. Hope this helps.

      Lights, cabviews, engine controls and sounds were all different from player versions, primarily to work around limitations of 1990's hardware and in the way MSTS was hard-coded to cap quantities and left to wallow unsupported. It was so disheartening back in the day to not even experience dynamic braking sounds from DPU units on the rear end.

      Of course, vendors are eliminating AI and Trail from today's new content as being unnecessary since MSTS limitations no longer exist when using the 'MSTS replacement' application.

        Very diplomatic phrasing, however, I'll risk some ire or mild rebuke and add this --- "MSTS replacement" = Open Rails Simulator...which most former MSTS users have phased into.

          Hi all (again),

          Thanks for all the responses! I've seen Open Rails stuff and will most likely tr it out in the near future, however, for the moment, I would like to get back up to speed on MSTS. I'm "relearning" things long forgotten, i.e. shape file manager and shapeviewer, for example.

          Additionally, I can't believe the quality of some of the freeware routes that have been released! Dare I say, some rival, and even surpass, some payware routes! WOW!

          Going back to engines, when I got away from MSTS, Jason Dilworth's SD40/SD40-2/SD45s were pretty much the standard for freeware, but there's some really nice newer models out there that demand attention. I recently discovered Danny Beck's release of some shape files here at TS, and have been cobbling together some modern engines, which is what brought me to inquiring about AI and Trailing .eng files.

          Thanks again for all the suggestions!

          Kind regards,

          Bill

            Bill, if you are re-learning MSTS, here's one important point to remember
            Do NOT install MSTS or any train sim stuff ( routes, trainset, etc..) in any of the Windows "Program" folders or other protected folders. Install everything in, for example, C:\TrainSim or whatever name seems reasonable to you.
            Read and follow these instructions at Steam4Me >>> https://msts.steam4me.net/tutorials/...ling_msts.html

              Just so people know, the free starter route has been updated. It includes Mullan Dash9s with current newer cabviews and some other rolling stock now. The 3 unit Gunderson 53 footers and the 3-unit 57' spines are also included for free now. Activities include a 2x3x2 grain train. All route textures are DDS only now, whereas the old starter had ace textures.

              Since they dumped the MSTS stuff and re-did their website, makes me wonder whether any old packs that were retained as OR releases now include newer OR physics?

                Thanks for the heads up on the starter route update. I can feel a download coming on to replace my original....

                  I am glad we are discussing ai and trail.

                  I have deleted ALL of my AI and trail loco's as I do not intend to use MSTS again.
                  The changes that this deletion brings makes it a bit longer to run an activity, but I like the file count in my sim set.
                  I have assembled a couple of utilities to assist with the modifications.

                    I would suggest combining both the original and new starter route's stock to get the most bang for your buck.

                    As to the original poster's question, MSTS-BIN phased out the trailing/AI engine file need before OR came around.

                        Not fully, when average light counts went from 24 or so to 50+ today per loco. Yes bin raised the ceiling, but we still hit it often enough.

                        I would scram the combining of both starters too. Everything is a repeat except for the Gevos that are broken anyway (missing the brakewheel) and those 48 foot Thralls. The folders in the new starter are named so Mullan and Seligman ORTS routes can get added to the same install and wrap around the starter stock and the acts for the starter still work. Motive power is from Mullan and wagons are from Mullan and Seligman ORTS

                        You start combining starters and you end up with duplicate car numbers in many directories with different names

                          Some activities and consists need to be fixed first. :-)

                            LOL The trash can solves that. It does wonders for your file counts, too. Trust me, not all activities are diamond grade.

                              I'll admit, I didn't run acts all that much to be honest, so it tended to never a problem for me. I can see how it could cause problems for other people though.

                              As for mixing the starters, I'll keep that in mind, and retract my suggestion. There is one case where two cars share the same name, but are in different folders, and have different paint jobs. While I haven't encountered any issues yet, there could be a conflict somewhere one day.
