Embedded Rail Tracks

Establishing reliable and sustainable public transport services is a top development priority for cities that face ever-growing urbanization trends and pressures to meet zero-carbon goals. Creating new transport corridors is always a challenge, so existing roads end up providing attractive routes for public transit. When this involves using rails, it becomes even more of an engineering feat.

Embedded Rail Tracks is a comprehensive resource on this high-performing type of trackway system, which provides minimal disruption to wheeled vehicles sharing the same public roads. The volume opens by briefly reviewing the history of embedded tracks, especially tramways and light railways, to then analyze the design, installation, and operation of existing embedded track systems. Accounts of reasons for failure and evidence-based maintenance and repair methods are also included. The book surveys the latest innovations, presents case studies, and includes considerations related to the environment, energy use, and safety that lead to insightful conclusions for future investments in more robust and less costly transport infrastructure.

"Track is fundamental to tramway operation, a truism if ever there was one. It’s surprising, then, that so little has been published about them, which makes Professor Lesley’s fascinating new book all the more welcome. He outlines the origins and development of street track, and the basic concepts of foundations, spacing, surfacing, and rails. If, like your reviewer, the reader has assumed that modern practice prevents traditional failings, then prepare to be disappointed. Throughout the book a gallery of horrors illustrates all types of worrying damage, much arising from the hammer-blow effects of heavy goods vehicles passing across the rails. Once distorted, even by a tiny amount, water penetrates the structure and soon distorts it. Some problems arose initially from inexperience amongst British civil engineers who tended to work, inappropriately, using their previous railway practice.
Opposition to new tramway construction often arises from the level of extended disruption caused during track-laying, not to mention the associated relocation of utility services, often inadequately mapped, and there are useful examples of current experience, as well as alternative approaches. Shallower rails are one expedient deserving further study.
Only one section of tramway is at present under construction in the UK (between Wednesbury and Merry Hill, mostly on private right-of-way) but it would be good for future contractors to be aware of the analysis here." (Tramway Review, vol. 38, no. 285, March 2026)
