Ticonderoga safehouse (called Ticon by Railroad agents) is a location in Boston in the the Commonwealth.
This skyscraper is a Railroad safehouse in the heart of Boston. Run by High Rise, the safehouse is for both Railroad agents and any "packages" they may be escorting to freedom.
An elevator in the plaza leads up to the safehouse, while there are some stairs that lead a locked door (it is locked from inside and requires going through the elevator to find the terminal that controls the lock). The main floor of the safehouse really has nothing of note except for two sets of stairs leading up, where there is a chemistry station, armor workbench and some spare rooms. There are also holes in the floor leading to lower levels, which is mostly ruined offices. By going through five floors, one can reach a door that leads back into the lobby of Ticonderoga.
Ticonderoga appears only in Fallout 4.
