T-60 Power Armor (Fallout 4)

T-60 power armor is a set of armor that can be obtained and/or built in Fallout 4.

Characteristics
This particular variation of power armor is much larger and bulkier than other recent portrayals, closer to the appearance of classic Fallout power armor. The helmet looks similar to the T-45d helmet, and the full armor does somewhat resemble the T-45d armor, as primarily seen with the shoulders. This variant of power armor is also shown to be at least initially powered with a Fusion core, and the entire back half of the armor unfolds to allow the occupant to enter, before sealing itself. Furthermore, the helmet provides an integrated helmet-mounted display that provides, amongst other things, a: health indicator, Geiger counter, armor component condition readout, and ammunition counter (displays both current magazine levels and reserve ammo capacity).

Locations
One can be found in Fiddler's Green Trailer Estate, however it is missing one of the arms and the helmet

Another suit, also missing an arm and the helmet, can be found at the National Guard Training Yard in a bunker-like building with two machine gun turrets on top of it. (requires master lockpicking)

Four suits can be found on the Prydwen, though in order to obtain one, you must join the Brotherhood of Steel for it.

Can be bought at the Atom Cats Garage with a flame paint job.

At around level 20, a blue shipping container near the northwest edge of the National Guard training yard may contain a full T60 suit. The exact type that spawns depends on character levels, so lower-level characters may find a T45 suit whilst higher-level characters may find an X01 suit.

Behind the scenes
The T-60 power armor was the first asset created for Fallout 4, back in 2008, although it went through multiple iterations over the years.
