“…It would probably be impossible for the UK rail industry to carry out such a project today. However, detailed research is ongoing although of a computational rather than experimental nature (Xue et al, 2005;2007).…”

This paper, based on a lecture given during tour undertaken in May 2014 of key railway establishments in China, consists of a brief introduction to the history and comparisons of railways in the UK and China, a description of rail speed-up in the last few decades in the UK, and notes of current high speed trains. Similar brief details are given of high speed in Europe. Brief mention is made of comparative railway safety. The development of high speed rail in China is discussed and the UK High Speed development plan is briefly introduced. The paper concluded that high speed train system has tremendous advantages in increasing the efficiency and convenience of transport without adding to carbon generation.

“…This dissipation is accomplished by the controlled crush of three components: (1) the push-back coupler, (2) the buffers made up of tubes or honeycomb and (3) the parts of the structure itself. Due to the different roles of the HE and LE crush zones, their characteristic parameters, even for the LE crush zone in different locations, should be designed differently for a certain crash scenario, which can be achieved through an optimisation method [23]. However, in the case study in this paper, the parameters for the structure absorbers in both the HE and the LE crush zones are considered to be the same.…”

In this paper, a three-dimensional nonlinear rigid body model has been developed for the investigation of the crashworthiness of a passenger train using the multibody dynamics approach. This model refers to a typical design of passenger cars and train constructs commonly used in Australia. The highenergy and low-energy crush zones of the cars and the train constructs are assumed and the data are explicitly provided in the paper. The crash scenario is limited to the train colliding on to a fixed barrier symmetrically. The simulations of a single car show that this initial design is only applicable for the crash speed of 35 km/h or lower. For higher speeds (e.g. 140 km/h), the crush lengths or crush forces or both the crush zone elements will have to be enlarged. It is generally better to increase the crush length than the crush force in order to retain the low levels of the longitudinal deceleration of the passenger cars.

“…Despite these consequences, injury reducing improvements concerning internal carriage design have been minor. Although improvements have been made in train construction and crashworthiness (16)(17)(18)(19)(20), developments and implementation of safe interior design lag behind.…”
