Thank you!  You both absolutely nailed. 

Thanks.

I have an older Bachmann loco.  It is a UP road # 824 diesel.  What the original Bachmann Product # was and what type of Diesel it is. It looks very similar to a B30-7 but there seem to be some differences.

A related question;  Is there a source of product #s, descriptions, photos, Year Manufactured of discontinued products.

I'd appreciate the help.
