A brief introduction is given to speed increase of mixed passenger and freight railway in foreign countries, and detailed description is made of technical data and experience accumulated from previous speed increase test in China in respect to track irregularity management.

And suggestions are given on problems relevant to the speed increase and reform of existing freight cars.

Modification for raising speed of NS100GA-5 rail crane braking system;

By analyzing existing problem of Xi′an-Baoji raising speed district catenary wire fork,with the various technical data of raising speed district field running catenary wire fork detection,this paper discussed raising speed district catenary wire fork changes in law and proposed some advice for raising speed district catenary wire fork inspection and adjustment.

By statistical analysis to a large number of data collected from the reliability test of 120km/h raising speed wagon,this paper,based on the theory of reliability engineering,elaborated the reliability of the tested wagon in the field of running safety,maintenance support,failure mode effect and criticality.

Increase Loading Quality, Ensure Operation Safety of Speed-up Trains;

Try our best to safeguard the safety of the sixth speed-up and the further development of harmonious railway construction;

Technical improvement scheme of 100 t telescopic arm crane for railway speed-up;

On basis of hard point elimination of OCS equipment in Harbin-Lanling of Beijing-Harbin line in the 6th speed raising of railway in large scale, and by comparison and analysis of data, puts forward the causes of hard points and measures on elimination of them.

Several lateral rigidity reinforcement schemes for 32 m simply-supported PC T-beams on existing single-line railway bridges under train speed raising are studied.

The speed raising and technical modification should, under the premise of safe transportation, make fully use of the existing equipment and try to reduce reconstruct work.

Carry on Speed-Raising Strategy,Enlarge the Scale of Speed-Raising Network;

Research purposes: The train control centre system for CTCS is an important signal equipment for achieving the sixth speed-raising in China railways.

From 1996 to 2004, five speed-raising projects have been implemented in the railway department.

The paper introduces revamping scheme and some practical experience of improving bite steel speed program in large-size round steel 40 and 50.
