“…Wendler also wrote a section in the Compendium on ERTMS, European Rail Traffic Management System, describing the effect of ETCS Level 3 (moving block) on rail line capacity (18). Mikulcˇic´and Mlinaric´ (19) and Corman and Henken (20) thoroughly describe all the moving block research that came after this point Recent studies on moving block have focused more on evaluating specific corridors. Van der Meulen developed a novel method to estimate moving block benefits that uses historic trajectory data from the existing fixed block control system, and used it to analyze various Dutch railway corridors (21).…”

As the nationwide installation of positive train control (PTC) technology has recently been completed, freight railroads are searching for ways to leverage the technology to improve their operations beyond increasing safety. One commonly discussed possibility is developing and installing PTC-based virtual or moving block control systems to increase the capacity of railroad mainlines as a lower-cost alternative to adding costly track infrastructure. Considering that demand for freight rail transportation is expected to increase by 24% by 2045, and that most major mainline routes are operating at their maximum capacity, substantial capacity improvements will become necessary very soon. Since U.S. Class I railroads are for-profit companies, choosing the most cost-efficient way to increase network capacity is a primary objective. Thus, the potential capacity and performance benefits of virtual and moving block train control systems should be evaluated in realistic scenarios. This study utilized a novel dispatching algorithm and detailed railroad corridor simulator to evaluate fixed, virtual, and moving block systems over the full length of a 2,000-mi long U.S. Class I railroad mainline corridor composed of a mix of single- and double-tracks. Moving blocks were found to have the potential to maintain current average train speed under a 40% increase in train traffic, and that five virtual blocks per fixed block achieved most of the performance benefits of moving block control.

Starting with historical references on traffic direction choice and how railway transport has become the reason for the predomination of righthand traffic on transport other kinds, the authors dwelled on the examples of traffic directions on automotive and partially air and sea transport and then went to forecasting the future in the definition of motion directions on railway transport, technical limitations of the systems with floor traffic lights and approached to the analysis of signalless systems of traffic control with fixed block-plots and then with mobile ones. It was shown that modern solutions for high-speed lines should exclude fixed signals. The main domestic and foreign examples for the design and exploitation of such systems at the world railways and subways as well as advantages and disadvantages in terms of traffic capacity and safety were demonstrated. The comparison of domestic and foreign systems of interval regulation of train traffic was made in the article final part. The fundamental similarity of Russia signalless automatic blocking system “ALSO” with all-European system ETCS L2, preserving block-plot fixed lengths but excluding the use of checkpoint traffic lights, was demonstrated. In addition, the common principles for “ABTC-M” system, used on Russia railways, and ETCS L3 system with mobile block-plots, which rules out the use of traffic lights as well as the devices for track section vacancy control, are indicated. Both systems exclude fixed signals and fixed block sections. Then the example of the systems at railways and subways with mobile block-plots was demonstrated – the systems work on the difference in braking distances of trains, running in the same direction. These systems ensure the shortest headway thanks to data on speed and braking curve of a leading train. But such systems have a lot of limitations in terms of railway operation and safety.
