Travelling from NV to DC for the first time.

Head to megaton and talk to Moriarty and the main quest will start.

I appreciate what you've done here with this mod Jax.  I'd like to preface this post by saying I mean no disrespect whatsoever, so if it comes off that way, please rest assured it's not my intention.  I'm a little confused as to why you instructed him to disregard my advice.  After my previous post, I took my own advice and checked out the switch in GECK.  It does handle more than just the movement, like you said, but that isn't to say starting with a pre-existing NV save will always confuse the hell out of the train.  You just have to step into the New Vegas wasteland before you try to use it.

About 10 seconds worth of digging led me to find out that if you step into the open New Vegas Wasteland, the inherent TTW quest script will update the global variables that keep track of which Wasteland you're in (bInDCWasteland and bInNVWasteland) to the correct values.  The script on the train switch only actually considers bInDCWasteland to know where you are and where to send you, and the bInNVWasteland variable isn't used at all outside of the main quest script toggling it on and off, so it seems redundant to even have it at all.  Everything you've written so far only uses bInDCWasteland, so deleting bInNVWasteland and removing it from the script would have literally no impact at all that I can see.

Since the aforementioned quest always runs, merely setting foot in the open-world Wasteland of NV will fix the globals instantaneously by setting the quest stage.  The quest stages also handles the radio disabling and the other important things that need to be enabled or disabled.

As I said in my previous post, my main file that I play TTW on was a pre-existing New Vegas file, so I'm not just taking shots in the dark here.  I'm speaking from personal experience.  I even went on to verify everything I've said here with another save that I havn't touched since installing TTW.  Teleporting directly to freeside and trying to use the train gave me the same problem as Coolmanbob.  Teleporting to freeside, stepping into the wasteland, then going to the train station made it work flawlessly from then on.  Also, the train, radios, and other important things have literally NEVER misbehaved on my main file, which was also a pre-existing NV start.  This is not surprising, as the scripts seem to handle everything properly once you step into the Wasteland exterior. (I've also started a new file with TTW installed as you recommend, played it quite a bit, and so far there's no difference in the behavior of these things.)

So again, I'm not really sure why you said to disregard my post.  Literally all you have to do to make a pre-existing save work properly is step into the NV wasteland exterior for a second to make the train work.  Hacking Moriarty's terminal and looking up the information about James will start the FO3 main quest as well, even if Moriarty himself has no dialogue options about it, so that's a non-issue. If there IS anything else that remains messed up after that, it definitely doesn't impact gameplay in a noticeable fashion.  Again, no disrespect is meant in this post, but if you're going to tell people to disregard my advice, I would appreciate you also telling them why.  As it stands, my advice was sound.

Because you didn't say ANY of that in your post. You said that somehow the switch had been swapped and that he should restart. Which he didn't need to. I forgot that the code you had mentioned was already in 2.2 so I told him the old way of fixing it.

Fair enough :P I was hoping to avoid writing all of that so as not to intimidate the guy if he's not familiar with GECK.  So rather than reading my ridiculous wall of text, we can simply summarize by saying this:

Go to the open Wasteland area of New Vegas before attempting to use the train and all will be well :)
