For remember that Freeman's limited is a crack train--its name a household word at least halfway across the land. He came to it five years ago--a prize for an engine-runner who had judgment, who had kept a good "on time" record for eight years with a less important passenger train; a man who knew the complications of a locomotive as you and I know the fingers of our two hands. It was not a "seniority" appointment. The "seniority" jobs come to the very oldest of the passenger engineers who, because of the very length of their service, are permitted to pick and choose the runs that would suit them best. These rarely are the very fast runs. They are more apt to be some modest local train making its way up a branch line and back, where there is little congestion of traffic and a throttle-man's nerves are not kept on edge every blessed moment that he is on the job. [Illustration: THE ENGINEER Oiling is too important a matter to be deputed, so he attends to it himself.] Jimmie Freeman did not pick his job. It picked him. It picked him because he had nerve, a steady head, good physique, a knowledge of the locomotive and of all of its whims and vagaries. And if his is one of the hardest jobs on the big road for which he works, he is perhaps only one of a half-thousand passenger engineers it might pick from its ranks and find fully able to measure to it. * * * * * An air signal over the engineer's head rasps twice; a starting signal. He pulls out the throttle ever and ever so little a way--a distance to be measured in inches and fractions of inches--and the limited is in motion. "We're sixty seconds late in getting off," says Freeman as he replaces his watch and settles down for the forty-mile pull up to B----, the first stop and scheduled to be reached in forty-three minutes. That means, with "slow orders" through station yards, as well as one or two sharp curves and a steep grade midway, that Jimmie will have no time to loaf on the straight-aways--he calls them "tangents." "Green on the high," says the fireman, as the big K-I ducks her head under a signal bridge and her pilot trucks find their way to the long crossover that brings her from the platform track in the tangle of the terminal yard over to a "lead-track," which in turn gives to the "main," stretching out over the sunshiny open country to distant B----.
