The marginal social cost of road and rail: Implications for rail investment and pricing [PDF]
, 1995 An important issue for transport policy is whether more investment should be devoted to rail schemes and less to road schemes and vice versa. This raises the problem of comparing the returns from investments in the two modes currently assessed on a ...

Impact of Wheel-rail Lubrication on Outer Rail Wear in Metro Small Radius Curved Segments
Chengshi guidao jiaotong yanjiu[Objective] For metro lines with high proportion of small radius curved segments and severe rail wear, lubrication can alter wheel-rail contact area friction coefficient and in turn effectively reduce rail wear, thus it is necessary to study the ...

Design of a low-voltage constant transconductance rail-to-rail CMOS operational amplifier
Dianzi Jishu Yingyong, 2020 This paper presents a rail-to-rail constant transconductance operational amplifier input stage. The proposed circuit changes the tail current of the input differential pairs dynamically for a constant-gm by using dummy input differential pairs.

Dynamic Response of Wheel-Rail Interaction at Rail Weld in High-Speed Railway
Shock and Vibration, 2017 As a main part of continuously welded rail track, rail weld widely exists in high-speed railway. However, short-wave irregularities can easily initiate and develop in rail weld due to the limitation of welding technology and thus rail weld has been a ...
