after going to a railspot yahoo group luncheon last weekend i got some info on the first roster numbers for teh bnsf sd70ace order. the person i talked to knows a mechanic at bnsf's argentine yard, which is where he got the info from. there are a confirmed 80 orders now, not just 30, and eventually when the first 100 are ordered , they will be numbered 9300-9399. after 100 though is anyones guess still, but at least the first 100 have a number series now!
