“…38 turnout with a moveable point frog designed for HSR applications. 9 Multiple gaps created greater vehicle accelerations than did single gaps on the same turnout. Although the presented conclusions may seem intuitively obvious, the authors highlighted the need to minimize and eliminate gaps on turnouts for high-speed operations and presented quantitative results to support their argument.…”

“…Many other countries, specifically those in Europe and Asia, can provide valuable insights into track design for high-speed operation. [8][9][10] However, there is still much to be learned about operating on shared track, as the combination of North American freight axle loads and more robust passenger car designs than those generally seen globally on existing high-speed lines exacerbates this challenge. 7 Both HAL and HSR types of traffic require special trackwork components that minimize impact loads.…”

Special trackwork, including turnouts and crossing diamonds and their components, plays a vital role in railway infrastructure by providing route flexibility to trains as they travel across a network. As the interest in shared rail corridors involving heavy-axle-load freight traffic and high-speed-rail passenger traffic grows, special trackwork represents a significant challenge due to diverging loading characteristics and design priorities. This paper presents an overview of the issues related with special trackwork for shared rail corridors, as well as an in-depth analysis of the relevant research to date. The relevance of different shared operation types and research needs are also presented. This study can be used to assist in the planning of new passenger services on freight rail lines, or vice versa, in the USA, and may also be relevant to shared rail corridor development in other countries.

“…12 turnout and presented a calculation method to evaluate the two-point contact. Cao et al [10] conducted research on the dynamic responses due to irregularity of Turnout is a weak link in a railway track system and different types of irregularities occur in the turnout zone. These irregularities could easily influence the trains' running smoothness, comfortableness, and even passengers' safety [11][12].…”

Abstract:The irregularity is a key factor affecting the wheel-rail contact geometry relationship. In this paper, we calculated the wheel-rail contact points at typical sections and obtained the longitudinal variation of the wheel-rail geometry relationship with the trace line method. The profile of the key rail sections was matched by cubic spline curve, and the shape interpolation was realized in non-controlling sections. The results show that the roll angles at each typical section increases gradually with the enlargement of track alignment irregularity. When the flange contact occurs, the roll angle increases dramatically. Proper track alignment irregularity towards the switch rail improves the structure irregularity of the turnout.
