Mav. 1916. Important Development the Penns on in Passenger Car Paintingylvania Railroad When the first all steel passenger car car tlien receive- was built by the Pennsylvania Railroad coats of varnish. : Company at Altoona in 1906. an entirely remaining in the new problem in painting was encountered, a smooth, glossy a certain number olufticient to fill all voidsflat color and to leavecoat of \arnish over VIEW OF OVEN, CLOSED, WITH CAR INM The expansion and contraction of steel,under the influence of fluctuations in tem-perature, is much greater than that ofwood. For example, a piece of steelwhich is seventy feet long at 0 degreeFahrenheit would be something like sev-enty feet, one and eight-tenth inches at100 degrees Fahrenheit. The expansionof wood under the same fluctuation intemperature would be less than half asgieat. Steel also conducts heat muchmore rapidly than wood, and suddenchanges in temperature produce rapid ex-pansions or contractions of the steel. Itfollows, therefore, that a painting systemwhich would be satisfactory for wood,might not be sufficiently elastic for the change in equipment fromwood to steel was made, it was practicallecessary to carry over the old system ifpainting and to apply the same principleon the steel car that had formerly beenapplied to woo
