RD REFERENCES THE SOURCE EVALUATIONS IN THIS REPORT ARE DEFINITIVE. THE APPRAISAL OF CONTENT IS TENTATIVE. (FOR KEY SEE REVERSE) aka 1953 1. There are installations at three points on. the Soviet side of the Soviet- Polish border where the wheelspan of railroad cars can be changed easily and rapidly. These points are Cherriyakhovsk (N54-38,E21.49)1 Brest (N52-07, E23p1i.2), and Medyka (X49-49,M'2-57) 9 the latter,,' located east. of Przemyslp' on the Krakow--Przemysl~Lvov magistral line, is the largest of these points. Wheels can be changed only on those-cars which have been built in Breslau since 1949. The majority of these cars, which are mostly between '20-and 30-ton capacity, havefo aarles.laced in airs near the front and back of the- ca-~ 2. At. these three frontier points are numerous branch lines, under which have been built tunnels about 2.2 meters deep and 250-300 meters long.. The tunnels are connected so that workers can pass from one tunnel to another; is not certain that there are walls between the tunneYaa; but,, if there ar,e they do not extend the length of the tunnels. Concrete pillars. similar in construction to steel railroad bridges support the surface railroad tracks; -the tracks on.. the surface correspond to those on the floors of the, tunnels, in that the gauges are identical and both have three rails, arranged- as shown in the attached diagram. `the equipment at these points is complicated but the work proceeds somewhat is follows-. The railroad cars are stopped with the wheels resting on a section of track which can be lowered by an elevator to the tunnel below the tracks; a hydraulic hoist is raised; into position to support the care while the wheels are changed; the wheels are, unfastened and lowered to. the tunnel floor on the rail elevator, wheels and axles of the desired. width being returned to the surface on the elevators, and"attached to the chassis. The hydraulic hoist is then lowered and the car is ready. The.entire.process requires five to seven minutes per car and 10 to 15 minutes for an entire train, no more time being consumed-than would be needed for.uncoupling or switching a locomotive. The crew is divided into groups of five, one group usually handling . two. cars. in the last paragraph are comparatively much too high. ..
