The object of this paper is to bring the actual operation of the New Haven single-phase electrification as closely as possible to those who are truly interested in its merits and faults. The duty assigned to the engineers of the New Haven railroad was to provide for the electrical operation of their trains. At the early period of April 1, 1905, when we settled down to this responsible task, the data in the field, upon which to base real conclusions, were about 5%, in comparison with the experience now available. The author covers "Major Faults," i.e. 1. Power house; 2. Insulation; 3. Circuit-breakers; 4. Line; and 5. Locomotives; as well as "Minor Faults;" 1. Generator burn-outs; 2. Distribution; a. Multiple-track circuits; b. Independent track circuits; 3. Contact wire; 4. Hard spots; a. Hangers; b, section breaks; c, deflectors; 5. Signal wires; and 6. Locomotive current collectors. He then covers the log of operation: 1. Electric passenger service; 2. Electricity versus steam; 3. Train-minute delays; a, table; b, chart; 4. Serious failures - over 300 train-minutes; 5. Engine repairs - a. Table showing engines in shop; 6. Engine capacity - a. Table showing trailing loads in excess of guarantees. 7. Engine-mileage - electricity and steam compared. Finally he covers the Electrification in Relation to Matters Other Than Traction and provides an overall commentary.
