Alco 1000 273 is seen parked outside the Bolton Maintenance Facility. The blue lanterns indicate it is being serviced and cannot be moved. Cape Ann's switchers tend to just be renumbered over their existing paint job, since they are considered not as visible as road engines. It may eventually get repainted in Cape Ann colors, but then again it may not.
This is an AHM. The odd road number indicates it is unpowered, so it is just here for scenic effect.
