🚍 Hello Transit Community 🚆 📝 Paper: "Decision support tools for effective bus fleet electrification: Replacement factors and fleet size prediction." Authors: Kareem Othman, Sarah Hamed, Diego Silva, Amer Shalaby and Baher Abdulhai This study develops prediction models to estimate the required Ebus fleet size to maintain same transit route services for the case of overnight depot charging, using data from Ebuses operating in the City of Toronto. The analysis reveals that Ebuses equipped with diesel auxiliary heaters are less sensitive to temperature fluctuations compared to battery-heated buses. Specifically, diesel-heated buses require a lower replacement factor (1.3) compared to battery-heated buses (1.4), with winter conditions exacerbating this disparity. Furthermore, the study employs vehicular, operational, route, and external variables to develop the prediction models.

Bi-modal battery trains are being proposed to reduce costs £3.5 billion could be saved for Britains railways, through the implementation of battery bi-mode trains, Siemens Mobility has stated. The new trains would use batteries on unelectrified routes, and overhead power wires on electrified routes. Such a change would make it quicker to replace diesel trains, when weighed against the costs of full electrification. Not only this, but Overhead Line Equipment can be installed more quickly than Rail Charging Converters. In a statement, Sambit Banerjee, joint CEO for Siemens Mobility UK & Ireland said: “Britain should never have to buy a diesel passenger train again. Our battery trains, which we’d assemble in our new Goole factory in Yorkshire, can replace Britain’s aging diesel trains without us having to electrify hundreds of miles more track in the next few years. So, on routes from Perth to Penzance, passengers could be travelling on clean, green battery-electric trains by the early 2030s.” Train operators including Chiltern Railways, Great Western Railway (GWR), Northern Railway, ScotRail, TransPennine Express (TPE) and Transport for Wales (TfW), are scoping the replacement of their old fleet of diesel engines. Through the research and modelling conducted by Siemens Mobility, it has been deduced that 20-30% of a line would need to be electrified, in order to make the Bi-Mode trains utile, however given that with the design of battery that would be used on these trains, they could charge their batteries to full capacity in a 20 minute time frame, when moving along electrified routes. 

East West Railway Company confirms it will be electrified and announces consultation East West Railway Company (EWR Co) has confirmed that the new East West Rail (EWR) line between Oxford and Cambridge will be powered by discontinuous electrification. Additionally, EWR Co has announced a 10-week consultation on the latest plans for the future sections of the railway. Electrification The EWR project had come under criticism for being a brand new railway that was set to be powered by diesel, undermining its green credentials. EWR Co had expressed its desire for a greener alternative and following the backing of the government in this week’s Budget it has now confirmed that it will be procuring hybrid battery-electric trains to enable discontinuous electrification on the line. Discontinuous electrification sees overhead line equipment (OLE) installed along the railway where possible. This powers the train electrically while also charging a battery on the rolling stock. In the sections where electrification is prohibitively expensive due to issues such as ground conditions or existing assets, the trains are instead powered by the battery. Discontinuous electrification has been a success on Transport for Wales’ Core Valley Lines upgrade, where the project was fully mapped out in advance and the rolling stock designed to the needs of the track - otherwise known as a system solution. EWR Co. has not confirmed when the work on electrifying the line will commence. Consultation EWR is being constructed in three Connection Stages (CS): CS1 is Bicester to Bletchley, CS2 is Bletchley to Bedford and CS3 is Bedford to Cambridge. EWR Co CEO David Hughes said: “We’re excited to confirm our plans for electrification, which support our environmental goals by delivering sustainable low carbon journeys and supporting the UK’s transition to an overall net zero carbon economy. “This consultation is a pivotal moment in our journey to create a railway that truly serves the needs of our communities and delivers sustainable growth for the region and the whole country by improving access to jobs, education and public services. "East West Rail represents a once-in-a-generation opportunity to connect communities across the Oxford-Cambridge region. We invite everyone to take part in our consultation and share their feedback on our proposals to create a positive legacy for future generations who will live and work in the area.” https://lnkd.in/eyVmhAEV
