So basically this is my issue.

I am at the Gypsus Train Yard inside the building and surrounded by a group of Blind Deathclaws. I have no idea how the hell I am supposed to get out of this mess. Anyone care to offer me some advice?

a stealth boy, but i'm sure you already thought of that . . .

i'd load up on chems, lighten your load as much as possible, unequip everything and try to make a run for it

Please forgive me if this sounds stupid as I have not reached the location you are referring to, but wouldn't blind Deathclaws be avoidable because they can't see you? And you can sneak out of there?

Again, not trying to prod, just seems like a likely answer.

Lure them into a death trap and cripple them with frag mines? Try to snipe them one at a time and pray to god for some good Sneak Crits/Crits? Stealth Boy? (If on PC) turn on God Mode?

It is next to the door so right as I come out it senses me I guess. Whatever the case is it is hunting me down quick.

haha yea i havn't messed with the blind ones yet either, is it like the giant thing in half life where you can throw a grenade far away and the loud noise will draw them all away from you?

Leave and level up a bit and then go back.

It took me a while but I basically took some advice from above and got down into my skivvies and just ran like hell until I feel down a small cliff type thing and they stopped chasing me. Unreal how frustrating that was.

hahaha good job! when all else fails, run for it in your underwear

LOL! Moments like that make this game great.
