The certification procedure for track maintenance machines

Issue 2 2008, Past issues / 8 April 2008 /

Track maintenance machines today are designed as standard railway vehicles and are subject to approval and certification according to EU directives. However, their main purpose is not transport on rail, but track maintenance work, track laying or track renewal. The enormous and continually rising expenditure surrounding machine certification which the EU regulations stipulate (presently around 5% of the price of the machine) are illustrated by the certification procedures laid down by the Federal Railway Authority (EBA) in Bonn.

The lateral resistance of the track (Part 2)

Issue 4 2007, Past issues / 30 July 2007 /

Ballast consolidation in the sleeper cribs raises the resistance to lateral displacement by approximately 7%. Sleeper-end consolidation raises the resistance to lateral displacement by 4%1. The Dynamic Track Stabilizer is the most effective method of raising the resistance to lateral displacement. It increases the resistance to lateral displacement by 30-40%. Tamping lowers the RLD by around 40%, ballast bed cleaning lowers it by about 50%. Soufflage (stone blowing as a newer mechanised technique) reduces the RLD by 50-65%.

The lateral resistance of railway track (Part 1)

Issue 3 2007, Past issues / 6 June 2007 /

One of the greatest achievements of railway engineers at the end of the 1960’s was the invention of long welded track. Up to that time the rails were laid in lengths and linked together by joints. The gap at the rail joint became smaller or larger depending upon the temperature. Vehicles travelling over the joint exerted a strong interactive force, producing high stress on the vehicle itself and a plastic deformation of the track in the area of the joint. A jointed track is subjected to heavy strain and therefore requires a great deal of maintenance…

Machines and technology for high-capacity lines

Issue 2 2006, Past issues / 3 April 2006 /

Whenever the speed or capacity of a line is increased or a new line is built, the application of appropriate track maintenance and upgrading procedures is very important to enable optimal and efficient use of the lines. In addition to that, a high level of comfort and safety has to be maintained on high-capacity lines. […]

New high output track renewals plant for Network Rail

Issue 1 2005, Past issues / 2 March 2005 /

Network Rail’s first new high output ballast cleaning system from Plasser & Theurer, delivered to time and budget last summer, has begun work on the Great Western main line which links London to Bristol and South Wales. It is the first of a series of new high output track renewal machines, with a total value of £90 million.
