N.s 25th ann. Operation livesaver unit just passed m.m. 187 at 5:45 p.m this is the chicago line and it is heading westbound! I don't know the number but I think its the same train as when it was with the cn units so ill check. GOOD LUCK!
Update: I'm 65-70% sure that the ID is NS 21Q.
there are 7 of these, numbered 9250-9256.
