by the intelligence and skill of man the arrow cross going proud of our mechanical equipment but we are proud i still of the men who keep it running in new haven rarely more  railroad at work we'll see to general faces railroad operations and railroad maintenance rain let's begin with the passenger locomotive backing into the yards to pick up the cars of the yankee cl cars meanwhile have been made ready for the passengers and having them clean and sanitary is rule a in the art of railroading repair shops here passenger cultures dining cars and grill cars are brought to be repaired all reb they're put through the latest processes of cleaning and sanitation there's an imposing background of work behind the picture of a smart modern car in a passenger  the ceiling of car windows and here we find a device of technical science to enable you to see better i can gaze at the scenery each streamlined window consists of two claims of glass held apart by rubber space these rubber spacers seal the inner services of the glass against the outside air between the paintings dry nitrogen is forced to keep them from being followed by condensing moisture the amount of groceries they can stow into the small pantry space that car dimensions permits would make a housewife think that it's all magic this railroad hundreds of passenger trains are made up every day in addition to hundreds of freight trains they operate through southern new england day and night with a was a woman in boston buying a bicycle for her nephew in new york and he'll get it the next day this takes us to the subject of freight train shipments a freighter into class also in switching the cars through the yard the powerful diesels which are the last word in this type of modern mechanism one of the busiest of workers in the realm of railroading practically a twenty four hour a day w you coronation of rail and highway transportation using as a load a trailer onto a flat car the trailer has picked up packages from all over boston to be distributed in new york ordinarily the tractor pulling a trailer would have made the trip to new york by highway but now the trailer is securely fastened on the flat car and then carried to the metropolis this avoids a truck trip to new york a large saving of gasoline and a rubber tire mighty important in these days of wartime shortages with rubber tires ration a signal to our which trains to and from new york will pass one of many sentinels of safety vigilant alertness twenty four hours a day when a train passes the signal and flashes the report to division headquarter carefully created it will go by ship but first it must be taken by rail down equivalent to the harbor and export angle of freight service industrial new england is of historic importance in the foreign the dining car is a place of leisurely luxury regaining yourself from a passing scenery provide entertain on their way up the how they go on to the top of the slope the purpose of all this is to classify incoming trains so they can be reassembled as other trains each to go to a different destination tracks where they join other cars to make new trains for other destinations w destination and this is done here cars unloaded and the merchandise is reassembled in other cars these cars are then attached to trains bound for many many by the engine house where running repairs are made we see another phase of railroading maintenance of equipment there are like repairs made at many points on the railroad and there are heavy repairs which are made in a great locomotive  a locomotive must be serviced and that occurs at many places along the line it requires great sample science to give the big drive wheels collection on the rails or wet and slippery the large activity everything possible is saved and put away for future use railroad economy laboratory tests are all right materials purchased by the railroad metals for example are subjected to exact in the chemical laboratories the magic of modern alchemy is applied to the checking of the materials in the interest of safety efficiency and economy and there's research to find new things new combinations new ways of applying chemical
