On my grandfathers veteran's compensation application, it has his organization and
Station as: [Co, B. 1st Bn. Rep. Trr, Cen, Camp Lee, VA.] and [155 Dep Brig].
Can any one tell me what the abbreviations stand for.

Hello,

I am not answering this from experience; however, I did some quick research, and here may be some of the possibilities:

"[Co, B. 1st Bn. Rep. Trr, Cen, Camp Lee, VA.] and [155 Dep Brig]"

Company B 1ST Battalion, Reserve Enlistment Program (or Representative?), Test Readiness Review Center, Camp Lee Virginia, 155 Depot Brigade

I hope this helps some - I doubt if I figured it out exactly, but I'm sure a phone call to the right person would clear this up for you. Have you tried contacting the Army directly?
