The small pipe leading from the T bend to the interceptingvalve conveys saturated steam for starting the engine. The re-ceiver and high-pressure steam pipe are arranged as usual. This locomotive will be put into service on a division adja-cent to Montreal and will be run opposite to another of thesame class, without the superheater. No special test other.
