lc_us.lua Script for crossing gate - where did it go?

I was checking out how to fix the level crossing gates for the US so they don't come in 5 minutes before the gates actually come down and came across a very old post here (2010). It mentioned how to do it on script file lc_us.lua which is supposed to be in the Kuju level crossings folder. It was there in the TS2013 version and experimented with it about two days before the upgrade for TS2014 came in. Well, that script file seems to have vanished into thin air now, though the gated signals still work (via their older default scripts).
It used to be under Kuju/RailSimulatorUS/LevelCrossings but that folder is now empty. In fact, now that I'm looking at them while typing this, all the folders under RailSimulatorUS are there, but they're all empty. I've tried searching for the file, and do find a bunch of .lua files, but nothing that seems related to the script I was originally looking for.
These are the directions I was originally trying to follow:
I know it has to be somewhere since the signals are following directions from their script, but I have no idea where that file is now. I'm thinking that TS2014 may have it under a different name now or under a completely new folder. Any ideas?
Thanks in advance.

In the Script component BP field, copy-paste the name of the LUA script. The default one is called lc_us.lua and you can find it in the LevelCrossings folder under RailSimulatorUS. I made a copy of it and placed it among the other files in my Source folder. I used it as is except for the following minor edits. Open your copy of the LUA file using Notepad and find these lines:
-- Trigger distances
WARN_DISTANCE = 800.0
CLOSE_DISTANCE = 550.0
PASS_DISTANCE = -100.0
