A sHEETIRoN ROOF TO BE PLACED INSIDE THE
PRESENT ONE.
There was n conference yesterday at the Grand
Central Station between President Depew snr other
officers of the New-York Central and the state
Board Of Railroad Commissioners. The result was
decision by the Central to try experiment Tor tho
ventilation of the Forty second-st. tnnhei IN a."
cordance with the suggestions OF the Board William
r.. Rogers, Isaac " Baker end Michael Richard wero
the commissioners present, while the railroad sHe
was represented by President Depew General Manager
John NJ Toucey, General Superintendent Iheodofo
Voorhees, and Chief Engineer Walter Katie OF tne
New.York Central and President Charles +. Ciask'
of the New York, New Haven. and Hartford
The experiment will be made in the side tunnel nom
Sxtyseventh 10 Seventy first sts, and the preliminary
work of estimating expenses and preparing plans mas
already been begun. As possible the physic'h
work will be undertaken. The plan. proposed oy the
Railroad Commissioners is the construction OF seeo
iron roof under the roof Of the tunnel so as 10 pro-
vide q chamber for the reception OF inc smoHe'
cnders ETC. A cut opening will be carried through
this secondary or artificial roof 10 allow the passage
OF the smoke stacks Of the locomotives, which VIII
escharge their smoke and gas into tho upper
chamber some method either OF pressure or ex'
haustion of the air from the chamber will be pro-
vided.
Sheet iron defectors will be constructed from thc
roof of the tunnel so 10 drive the smoke OF tno
engines III different dlfectOns 10 IL ID cAPo'A "" -
chamber between the present roof and the artinciA
roof The artificial roof will afford place Tor tho
accumulation Of cnders, which may be removed IRON
time TO time. The smoke will be driven out Oh inc
openings already existing In the tuhne''
II is claimed in behalf of this plan that ho
persons living along the line Of the tunnel
will be relieved OF the nuisance OF cnders, wme thero
will be no greater inconvenience from smoke
President Depew said yesterday "The plan recon-
mende, by the Railroad Commissioners Will Involve W
In considerable expense, but we propose 10 Ty IL.
II adopted, we will have to sink our tracks through
solid rock but we are willing TO do anything reasonable
to meet the wishes of the Commissioners Inc SOC
ton selected for the experimental test OF the socaeo
hood system OF ventilation is the one best adapted LOT
the success of the trial.
"But excepting this piece of the tunnel from sixty
seventh to Seventyrs the roof OF the Tunnel does
not permit of the introduction of AN artificial rooi
unless the tracks Of roads lowered ana as ey
are laid upon rock some idea may be formed OF inc
expense that would be required In extending tne sys
tenn throughout, well Of the interruption 10 Vci
while the work was going on. The central onhoers
saw that they are willing 10 adopt any pan IDae
PROMISES TO Weld satisfactory results and the outcome
of the experiment will be watched with interest by v
ellers who are compelled 10 undergo the discomfort
the heat smoke and clnders connected with the prent
ODeratiOn of the tunnel"
