dedicated rail propulsion battery architectures? What is the anticipated energy capacity range of the rail battery systems involved (kWh or
What type of propulsion BESS systems are expected to be supported? Are these conventional UPS-style systems or dedicated rail propulsion battery architectures?
What is the anticipated energy capacity range of the rail battery systems involved (kWh or MWh)?
What is the intended operational goal after de-energization? Is recovered energy expected to be stored and reused through secondary BESS or grid integration methodologies?
Is the expectation to develop a fully integrated all-in-one mobile discharge platform, or a modular deployable system architecture?

Question 1 (Q1) - The BESS propulsion system provides tractive energy for locomotive or multiple unit trainsets. BESS propulsion systems replaces traditional diesel engines.
Q2 - These are dedicated rail propulsion battery systems
Q3 - BESS for rail propulsion range from 400 kWh to 2.5 MW.
Q4 - The intended operational goal after de-energization depends on the health and state of the BESS. The de-energizer is intended to be used at accident sites or in maintenance shops. In scenarios where it is used in maintenance shops, it is expected that the batteries be fully functional after de-energization.
Q5 - It is not expected that the recovered energy be stored or reused. However, for cases where the system is used in maintenance shop the recovered energy may be useful to the railroad; reusing the capture energy could be a secondary feature of the system
Q6 - The question is not clear to me. The de-energizer is intended to be a mobile platform that can be deployed to rail accident sites or used in rail maintenance shops.
