I have a consist (3 boxcars) coming into Portland, Maine from Boston(created by portal). The consist arrives in the Portland (Rigby) yard. The engine returns to Boston. Sometime later I want a local (yard) engine to deliver each of the three boxcars to three different customers. My problem is, how do I get the identification of one of either one the two boxcars which are available for coupling (3rd in middle of consist)? The Boston Dispatcher has sent me the IDs of each of the 3 boxcars. However, there is no info on which is a specific lead or trailing car.
