| vanIa railroad tunnel under New YcrA City has been awarded. The work involves placing all the electric par. aphernalia in the tube extending from Harrison. N. J.. through Thirty fourth street and out to Jamaica, l.. l., and equipping the train service. The railroad company stipulates that the work must be completed iu % months. It is the present hope tU
 have trains running in the tunnel within two years. The contract calls for 100 electric locomotives, tho largest ever made, each with ca pacity of 4.000 horse power It is es- timated that, hauling the heaviest
 train that may be made up. they will
 be capable of 120 miles an hour.
 The tunnel will be able to handle ]. 900 trains day The Pennsylvania officials have left it to the contract ing company to decide whether to install the third-rail or overhead sys- tenn and the latter will probably be chosen. The company will build a power house at Long Island City, with ' trenches for reserve power at other points, one probably in Manhattan. IL Is estimated that about 250. 900 horse power a day will be required to oper- ate all the trains to be run through the tunnel.
 The Pennsylvania railroad company will build branch tubes to other rail road terminals, which will be equip ped. Before the entire work is com pl1ted. 1t is estimated that the Penn sylyania railroad company wIll nave n he, tAfNn y,T. trical equipment
 To demonstrate in practical man. ner the advantages of the electric car. risge for use on busy sre ; where the traffic is congested ard for work in which many stops are -eoumeo, such as a lady's shopplps trip. lhis week 9 novel test was made in Bos- ton. Two cars, one an electric and the other a gasoline tourer, were started at the same time from the same point. They were to cover a predetermined route of about ten miles over many of the downtown streets. each making 20 stops. The cars travelled the route in opposite directions. Owing to the traffic on such streets as Fremont, Washington and others selected high-speed was out of the question so the decision rested largely upon Quickness in sun- loading and loading passengers and stopping and starting the car. Each machine carried passengers, who dis mounted at the prescribed stops.
 ' The electric car made the trip in one hour and one minute, and finished 13 minutes before the gasoline car put in an appearance. The route was through Boylston, Fremont, School, Washington, Summer and High stEsetS, A A1..eaaaant'c avenue, Summer Bed ford, Washington, Boylston streets, Dartmouth street, Huntington and Massachusetts avenues to Boylston street. The quickness with which Iils electric cur could he stopped and the case with whicn it wound it's way among the othe vehicles was sul piise to the lassc- gers. The gasoline car made the s'o. easily and quick iy but could not get away and threan through ne tiafiic as rapidly as the electric. Even on the comparatively clear stretches the gasoline car had little the better of the electric.
 The Prussian State-Railways ad- ministration has adopted some acculn- ulator cars for use on main, lines, and also for branches where a sufficient amount of traffic can be secured, in order to provide means for the coli- veyance of passengers to internedi- ate stations in addition to those car ried by the through trains. The sys- tenn of using accumulators will light en the loads on long distance express trains in populous districts, and will provide conveniences for communica- tion with the suburbs of large towns. It may serve as a substitute also for steam traction in sparsely populated localities, where single coach, which nay be run at such intervals as the traffic may call for, will suffice for all requirements.
 The first double coach, to be driven ! by means of accumulators on main lines was recently tested on the sec ton of the railway from Templehof | to Zossen, and the train W Il be placed | in service between Insterburg and Konisberg. It is composed of rwu short-coupled, doubleaxle carriages,
 each of which contains a battery of accumulators in the front compart- ment In consequence of the entire iseparaticn of the space allotted to the accumulators from the part of the
 train intended for passengers or rail
 way servants, all damages to the car riage or tets interior fittings Is avoid
 ed, and also all annoyance to the
 passengers by acid fumes.
 The double coach has standing and
 seating accommodation for 100 pas
 sengers, one-haIf being set apart for lthfrd-class and the other for the
 fourth class now introduced into Prus
 sia In addition to this, each half oi the train has a space for the guard which at the same time serves as the only entrance for passengers tc
 the compartment; this arrangement
 being the same as in the case of the
 street railways.
 Tae electricical installation is oUn
 structed as simply and durably as pos
 sible, in order that it may necessi
 tate but little skilled technical super
 vision The battery, which, as al
 ready stated is placed in the fore com partment, has a total capacity of 36' ampere-hours, which enables a dis
 tance of about 100 km- to be covered
 by a single charging. The two main current motors, with shifting poles are each rated at 80 horsepower fo one hour, and run at maximum speed of 50 km- At each pole of tha
 battery there is switch inserted, b,
 means of which the entire train fiji
 t.ngs can be disconnected from thu
 hastery, and by an alteration in th' switch it becomes possible, after ons half of tho hafferv has bpen sW fc1nes |, off. to run on the other half alone.
