Lettering is MILW maroon or yellow. They run on black roller bearing trucks. Classed as “RBL” and part of the 2600-2654 fifty car series, they have specially equipped interiors and are not suitable for general service. Over twenty years later, 20 cars from this series were still operating with MILW reporting marks in the same paint scheme.
