Of transformers, there are to be seen a complete set ofthe companys O.

W. machine from 2,200 to 110volts, at which potential they supply the four incandescent signs. One of the most novel attractions in the Electricity Build-ing is a high voltage sign. It consists of two large glass platescovered on the back with metal foil, with the name Westing-house in its center. An alternating pressure, having a maxi-mum of volts, is applied between the foil on the back and Vol. XL, No. 8 RAILROAD DIGEST.

As the potential is raised afringe of violet light appears about the letters which, graduallyincreasing in intensity, culminates in a myriad branches light-ning discharge that plays continuously over the surface of theplate and is accompanied by a continuous crash not unlikethunder. Among the railway motors included in the Railway Exhibitare a Westinghouse 56 motor, for heavy suburban and inter-urban service; a oO-C, for heavy railway service, and a 09motor for city and subrban service. The 50-C motor is pro-vided with a special cradle suspension from the car axle, thusremoving the weight of the motors from the car trucks. Thisarrangement minimizes the wear of the rails, increases the life
