M/W EFFICIENCY ON UNION PACIFIC
The best yardstick in measuring the success of a maintenance policy is to compare the quality of the track and roadbed structure, with the maintenance cost, based upon the tonnage of traffic and the speed. Charts are updated each year to compare UP maintenance-of-way operating expenses with those of six other major railroads which have comparable traffic volumes, operating conditions, and so forth. Equipment is updated each year with the latest generation of equipment available, without over- mechanizing. The quality of day-to-day track-maintenance work that is done between the periods of out-of-face heavy program work has more to do to insure the best track conditions at the lowest over-all cost than any other single factor. Section gangs are assigned over the entire railroad to do the day-to-day maintenance work. The section forces mark the bad ties. The number of ties marked in each area is tabulated before the annual tie-gang program is established. UP M/W department is having a problem getting adequate on-track time for its mechanized track gangs engaged in out-of-face work. The only solution to the problem is to maintain close communication with operating department people to get just as much time on the track as possible. UP is a relative newcomer in the use of continuous welded rail. The road has firm rules governing the heating or cooling of the long strings. By vibrating the rail at the same time that it was being heated or cooled, frictional resistance is overcome and the rail is permitted to expand or contract the desired amount at the end of the string. Another area of pioneering for UP is in the use of glued or bonded insulated and closure joints between CWR strings. UP hopes to purchase a self-propelled car capable of testing track at 35 to 45 mph.
