motor which he said was on one Of his
metropolitan cars operating on trial
track at Trafford Park. England.
LIGHT FOR PHOTOGRAPHS
The Cooper Hewitt mercury vapor lamp
and conyertor which constitute two Of
the latest electrical developments made
part of the exhibit The lamp IS the most
efficient artificial light known and its
striking characteristics are economy and
diffusion for general Illumination The
light Is procured through the incande-
scence Of the vapor Of mercury. IL has
been extensively applied to the illumi-
nation Of railroad shops, piers, machine
shops, etc.
The Cooper Hewitt mercury vapor con-
verter Is used for converting alternating
current 70 direct current. This light was
the spectacular feature Of the exhibition,
and added special interest in that
photographs Of many distinguished per-
sons were taken by It, among them be-
ing Nice-President Fairbanks, Colonel
Thompson, Vice Admiral Lord Charles
Beresford, Sir Charles owen, General
manager Of the London Southwestern

Vreeland of the New York Metropolitan
railway, Hon. II. X Porter. of Pittsburg,
Admiral Schley, tho Chinese Minister,
and Postmaster General Corteiyou. The
Postmaster General was especially inter-
ested in the various safety appliances ap-
piled to the railway mail cars.
From Washington the delegates VIII
visit the great works OF the Westinghouse
Companies at Pittsburg the Manchester
and New Castle Of America, where every
facility win be afforded for the inspec-
tion OF the apparatus under construction.
These workshops are reputed to be the
most perfect In the world for the manu-
facture of railway appliances and to their
favorable situation with respect to fuel,
raw materials. etc. as we'll as their ex.
ceptonai advantages for manufacturing
and shipping is ascribed the phenomenal
growth-of these Industries.
HOME OF THE AIR BRAKE.
AT Wilmerding near Pittsburg, the dele.
gates will inspect tho home of the ali
brake, the capacity OF which plant is one
brake per minute. and which has supplied
over a million and half air brakes now
In service throughout the world At the
electric works nearby Will be seen every
essential detail for the generation, trans.
mission ana utilization of electric energy
on May 18th viii be exhibited a on,
! hundred and fifty car test rack for tn,
purpose Of demonstrating the dnerenc,
m operation of the improved type as com.
pared with that OF the standard quick
action triple valve. These improved valve.
reduce the time of service application OF
a fifty car train practically one-half.
Tests will also be made on a hfty-cai
freight train, equipped with the improved
type OF triple valve the friction draft
gear the automatic brake, slack adiustei
md the automatic car coupler. Thes,
tests will be made on the Interworx.
Railway just outside the factories. Tn,
friction draft gear provides yielding
resistance of several times the maximum
tractive power of the largest locomotive
This great capacity TO absorb shocks ii
train handling prevents the breaking OF
draft rigging and couplings and prolongi
the life of the cars. The automatic ca

The visit win afford an exceptional op
portunity for an inspection of the prn
cipal railway appliances which represen
over quarter of a century of Americai
invention and skin and the Pittsburl
trip will no doubt prove an importan
event in the annals of the Internationa
Railway Congress.
