Train positioning using video odometry... Elimination of errors in video odometery induced by pitch and height; (b) Robust calculation of (i) the train velocity and (ii) the track curvature; (c)....
Railroad spiral design and performance... The results illustrate: 1) the dynamic disturbance caused by the discontinuity of first derivatives of track curvature and twist with the conventional ‘linear ’ spiral; 2) the better dynamic performance of other simple forms of spiral including the virtually perfect performance...
Track train dynamics analysis and test program: methodology development for the derailment safety analysis of six-axle locomotives... A user oriented software package was developed as part of the methodology and was used to study the effect (on operational safety) of various locomotive parameters and operational conditions such as speed, tractive effort, and track curvature....
Effects of the embankment topography and track curvature on ground vibration boom from high-speed trains...paper.The present paper investigates the effects of the embankment topography and track curvature onground vibrations generated by high speed trains travelling faster than Rayleigh waves in the supportingground....
