The B30-7 was the second B-B Dash 7 to be introduced. Production began in 1977, The B30-7 was a sucessful locomotive with 199 standard B30-7's outshopped, 58 B30-7A's manufactured, 22 B30-7A1's produced, and 120 cabless B30-7A(B)'s built. The B30-7' started production using a 7FD16 prime mover, then, like the C30-7A, the B30-7's prime mover was changed to a 7FDL12 prime mover churning out the same 3,000 hp. The B30-7 and other GE Dash 7 locomotives have become somewhat popular with shortlines. A B30-7 (standard) is rostered by the West Tennesse (WTTN), also three B70-7AB's are on Central Michegean's roster.
