I just realized I goofed like 6 hours back and I'm hoping there's something that can be done. I am currently on the BoS storyline and was hoping to at some point acquire some MK5 Railroad armor during the battle of bunker hill. Trouble is I immediately got myself banished from the institute thinking completing synth retention had no affect on my progress (not realizing it was the precursor to the battle of bunker hill). So now here I am with no option for the battle of bunker hill, and the railroad is dead already, is there any other way to acquire said armor or is that it?

If your friends with Bos the RR sometimes attack the military checkpoints.

Or there is that sky scraqer safe house. They mite have some

reverse pickpocket Glory, she wears Railroad heavy.

If by skyscraqer you mean Ticonderoga Safehouse, I just paid them a visit ( they were not happy to see me), no railroad armor there.

As for pick pocketing glory, I killed her already, she had a mk1, I'm after a mk5.

I went with the institute and got a mk 5 when RR attacked a checkpoint, not as good as my courser armour with ballistic weave though so I put it on Cait.
