Complete sections of trackrails and crosstiesmay be prefabricated and laid in the track by mechanical means. Rail-grinding machines run over the track to even out irregularities in the rail surface. Track-measurement cars, under their own power or coupled into regular trains, can record all aspects of track alignment and riding quality on moving charts, so that maintenance forces can pinpoint the specific locations needing corrective work. Detector cars move over the main-line tracks at intervals with electronic-inspection apparatus to locate any internal flaws in the rails.
Mobile Ballast Crusher Machine. Crushed stone of good quality is quite universally regarded as having properties which make it especially desirable for ballast purposes and in normal periods of activity the production and sale of railroad ballast forms an important part of the business of crushed stone producer.
Railroad fixed plant consists of much more than the track. More than two-thirds of Germanys new Hannover-Wrzburg high-speed line, for example, is in one of its tunnels or bridges or in cutting excavations. Railroad civil-engineering forces also are concerned with constructing and maintaining thousands of buildings, ranging from small sheds to huge passenger terminals.
The designer of a railroad bridge must allow for forces that result from the concentrated impact that occurs as a train moves onto the bridge the pounding of wheels, the sidesway of the train, and the drag or push effect as a train is braked or started on a bridge. These factors mean that a railroad bridge must be of heavier construction than a highway bridge of equal length.
As axle loadings become heavier and train speeds higher, bridges need to be further strengthened. Another major objective in modern railroad-bridge construction is the need to minimize maintenance costs. The use of weathering steel, which needs no painting, all-welded construction, and permanent walkways for maintenance personnel contribute to this end. In the advanced countries there has been a widespread trend toward reinforced concrete structures.
Diesel and electric locomotives require few maintenance shops as compared with steam locomotives. Car shops, too, have been reduced in number and made more efficient through the use of process-line techniques. It is usually more efficient to construct new shop buildings rather than convert old ones to handle modern types of rolling stock.
Although very expensive, tunneling provides the most economical means for railroads to traverse mountainous terrain, to gain access to the heart of a crowded city, or, more recently in Japan and Europe, to project a railway across a maritime strait below its seabed. Railroad tunnels, however, confront the construction engineer with some unique problems, particularly in the ventilation of very long bores and in mastery of difficult geologic conditions.
