New Haven, Dec. 12-The eIectrifi-
 cation of tKe New York, New Haven & Hartford Railroad from Stamford
 to New Haven will be completed by
 July next, if weather conditions and
 delay. in delivery of materials do not
 interfere with the progress of the
 work, so it. is officially stated from
 the offices of the road here,
 According to the engineering de-
 pa.rtrnent of. the New Haven road the progress of the work up to date in cluded the completion of 75 per cent. | of the excavation and concrete pedes- 1 tals for the overhead bridges. Thirty | per cent. of the structural steel in | such bridges has been erected and the erection of the overhead catenary sys- | tenn of wires will be begun very soon. i Approximately 200 men are engaged | at present in the work which. is being
 done under the supervision of the en- l gineering department of the road. The i Johnson Clifford Company has the cop- l tract for the foundations and for fur nishing and erecting the steel catenaTy bridges. s The engineering departm ent | of the com pany is installing the over head wires itself. ! Improved Wiring System.
 l The new electrical rolling equip ment will be substantially the same
 as now in service between New York I and Stamford, with such improve
 ments in details as are indicated by LII ovenheada | system between Stamford l and New Haven will be subs tant tally | identical with that recently comp mpleted
 on the Harlem River line and the
 railway. 1t differs quite materially
 from the original identification be ] tween Stamford and Weodlawn, more 1 particularly in the adoption of a com
 pound catenarys system of greater
 simplicity as con1pa red with the so-
 called double catenary'' system sup- porting conductors and contact lines
 by triangular hangers as contained in l the older system.
 In the 1zter installations bhe me
 chanicaI and electrical messengers are separated from each other by insula- 1 tors bearing a test pressure of 10000
 volts, thus providing an electrical fac
 tor of safety of 10 for the actual work l ing Il, GOO volts. The extension of
 electric operation to New Haven will
 avoid the necessity for the present l transfer of steam and electric engines at Stamford, and will thus avoid the 1 delay incident to the present inter mediate transfer. | Other Improvements & 1 The most salient novel features in ] the extension comprise a reactive ar | rangement of wires which while | greatly increasing bfae radius of trans I mission power without increasing the difference of potentiafsg between con-
 time eliminates the effect of electro | magnetic induction on adjacent tele- | graph and telephone systems, which | has heretofore caused much trouble
 and Interruptions to service. In ad- l d1tfon, the general arrangement and 1 details of the overhead construction | have been greatly improved. r | The active pushing of this work 3to | such early completion means a great l benefit to New Haven and to all who travel over the main travelled high | way between this city and the metro
 polls. It also means that the electri- fication will be in full working opera ton now before the new sta tiorl is ready so that there will not have ito be any steam engines drawing pas senger trains into and out of the sta- tiOn
