INTERSESSION ACTIVITIES OF THE IRCA 1977-1978. QUESTION 2--TECHNICAL AND ECONOMICAL COMPARISON OF THE VARIOUS TYPES OF TRACK LAYING: BALLASTED TRACK WITH SPECIAL CONSIDERATION ON THE DIFFERENT TYPES OF SLEEPERS TO BE ENVISAGED; UNBALLASTED TRACK

This is a report of a survey conducted for the IRCA on track structures, track laying and track maintenance on the following railways: Algeria, German Federal Republic, Argentina, Austria, Belgium, Cameroons, Chile, Ivory Coast, Denmark, Spain, France, Italy, Luxemburg, Morocco, Mauritania, Netherlands, Switzerland and Hungary. For virtually all types of heavy and fast traffic the following are found to be the trends: Rail is 50 to 60 kg/m installed in welded strings and inspected ultrasonically at the mill. Ties may be hardwood, twin-block concrete or monoblock concrete with choice primarily economic. Fasteners must be elastic. Ballast must be of very hard crushed stone at least 20 cm thick. Slab track technology still is evolving. Maintenance costs are lower with concrete cross ties. Conventional track, optimized from the choice of ties on each railway, still remains the most reliable structure.
