The Public Transport Authority in Perth just selected Alstom as the preferred technology supplier for network-wide rollout of CBTC. What was notable during the procurement process was a fierce competition between the three remaining big global players, besides Alstom also Siemens Mobility who was the second shortlisted CBTC supplier, and Hitachi Rail (formerly Ansaldo STS) who used to be the incumbent signalling supplier in Perth for interlockings, Automatic Train Protection and the PTA's traffic management system. That competition in the face of global fight for bidding resources was a strong confirmation of the procurement strategy in Perth. Tendering the entire network in one go, a total of 250 route kilometres once all the current METRONET network extensions have been built, makes this project one of the largest CBTC contracts worldwide, consequently attracting all major suppliers to come up with their A game. Why did Alstom win against the two others? Only the PTA knows, but it is an educated guess to assume that two factors played a very important role. Firstly, the partnering of Alstom (which meanwhile includes Bombardier) with DT Infrastructure (formerly Downer). And secondly, related to that, the fact that Alstom and Bombardier-Downer have responsibility for the PTA's entire suburban train fleet. Alstom by building the latest generation C series trains, and Alstom/Bombardier with Downer maintaining the older A series and B series fleets. Why is that important? Some may argue that the retrofitment of trains with CBTC could be easier if CBTC and trains come from the same stable. Now be that as it might be, what is certain is that timely fleet fitment with onboard CBTC is critically important for the success of the CBTC rollout. Especially when migrating to a pure cab signalling solution with removal of lineside signals it is essential that all regularly operating trains are fitted with CBTC when the CBTC infrastructure goes live. All the best for what looks like a promising start for the PTA's transformation to a high capacity railway powered by CBTC, the archetypical technology for high capacity signalling. #australia #perth #cbtc #highcapacitysignalling #docfrankrailservices

A. ETCS, or the European Train Control System, is a key component of the European Rail Traffic Management System (ERTMS). It is a standardized signaling and control system designed to improve the safety and interoperability of trains across Europe. Here are some key features of ETCS: 1. Automatic Train Protection: ETCS automatically manages train speed and ensures that trains do not exceed safe limits, significantly reducing the risk of collisions and accidents. 2. Interoperability: By standardizing train control systems across different countries, ETCS facilitates seamless cross-border rail operations, allowing trains to travel across various networks without needing to change equipment or systems. 3. Levels of Operation: ETCS is implemented in different levels (Level 1, Level 2, and Level 3), each offering varying degrees of control and communication between trains and the track infrastructure. a. Level 1 relies on trackside signalling and balises (information transmitters) to communicate vital information to trains. b. Level 2 provides continuous communication between trains and control centers using GSM-R technology, allowing for real-time updates and more efficient train management. c. Level 3 is still under development and aims for a more advanced system that could allow for a system without fixed block sections, increasing line capacity. 4. Safety and Efficiency: ETCS enhances the overall safety of rail transport while also aiming to improve the efficiency and capacity of railway networks. By implementing ETCS, rail operators can achieve a higher level of safety and operational efficiency, paving the way for more integrated rail services across Europe.

This is the clearest explanation of fixed block vs moving block I’ve ever seen. It takes many words to explain this concept, but this short animation makes it extremely clear.

That's a really good video about fixed block and moving block railway signalling and train control systems. #movingblocksignalling #fixedblock #CBTC #PTC #Alstom #HitachiRail #Signallingsystems #CommunicationSystems #TCMS #RollingStock #Siemens

This is how advanced railway signalling and train control systems safely increase the rail network capacity. Capacity is a key consideration in railway signalling, and there are two main approaches used: fixed block and moving block signalling. Fixed block signalling divides the track into sections, and trains are not allowed to enter a section until it is clear. Moving block signalling, on the other hand, uses communications between the train and the signalling system to calculate a safe distance to the next train, allowing for more efficient use of track capacity.

Credit to Rail Projects Victoria for what is likely a compelling video. Visual aids can make complex technical concepts like signalling systems more accessible and engaging for a broader audience. This post effectively conveys how technology is revolutionizing rail networks. It’s an excellent educational piece for professionals, enthusiasts, and anyone interested in the future of transportation.

"Excellent insight! The moving block system stands out by maximizing track utilization and enhancing safety and efficiency compared to the fixed block approach."
