Probably the most elaborate exhibit train that has yet been sent out was the Safety First Train of the Department of the Interior, which toured sixteen states during a period of four months and was visited by over a half million people. This train, which was furnished by the Baltimore and Ohio Railroad, consisted of twelve steel cars, including a sleeper and diner, and was hauled by two powerful passenger locomotives. Six governmental departments and the American Red Cross had exhibits relating to safety work, the purpose of the tour being “to acquaint the people with the work that the Federal Government is doing every day to protect its citizens against injury and death, and with the measures it takes to promote the health and comfort of the people.” TROLLEY TOURS Campaigns have been conducted on interurban lines in several states. For about three months the Woman’s Committee of the State Council of Defense ran a Children’s Year Special over much of the interurban trackage of Michigan, in the interests of better babies everywhere, and as a help in saving Michigan’s quota of the one hundred thousand babies the Children’s Year was to save. The car was divided into three sections--the first part contained an exhibit, the second a compartment in which babies and children brought for tests were undressed and dressed, and the third a model examination room where tests and examinations were made by skilled physicians and trained nurses. The Woman’s Committee of the State Council of Defense in Massachusetts also ran a children’s welfare car. The interior of the car was given over to exhibits of literature and posters on food conservation and child welfare. The front and back platforms were enlarged and surrounded by arm railings. On one platform a kitchen was arranged, where a lecturer gave actual demonstrations of the various food substitutes; on the other a trained nurse instructed mothers upon the care and feeding of children in wartime.
