Without fast travel, Railroad HQ is a real pain to get in and out of. This mod adds a manhole cover that leads directly into the main headquarters. When you visit Railroad HQ for the first time, you'll be able to retrieve a key from Tinker Tom's red-lit firing range area that unlocks the ladder hatch beside it. To come back in, all you need to do is look for the Railroad HQ map marker -- the manhole is right there next to the lantern, by the truck with the railsign on the hood.

Just an ESP -- added objects only, fully cleaned with FO4Edit (meaning there won't be any Vertibird bugs or precombined mesh conflicts).
