Top-of-Rail Lubricants: Potential Risks and Benefits [PDF]
i-RISE 2018, 2018 Top-of-rail (TOR) lubricants represent modern approach for friction modification between wheel and rail. The main goal of this study was to investigate potential risks and benefits associated with the application of these products, especially in terms of adhesion, wear, and noise. For this purpose, both laboratory and field experiments were carried out.

Uncovering the Real Potential for Air–Rail Substitution: An Exploratory Analysis [PDF]
, 2012 While air to rail substitution is much discussed, in the literature and in the policy debate, there has still been no attempt to quantify the potential for such mode substitution in order to examine the extent to which High Speed Train (HST) might address the main problems faced by the air transport industry: the capacity shortage on the one hand and ...

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

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 ...
