There are now functioning, successful solid state battery prototypes reportedly made by a few companies (e.g., QuantumScape & Samsung), and only 4 to 5 years away from being mass-produced. Smaller, lighter, greater charging density, greatly reduced charging time, longer-lasting as dendrite formation is limited or eliminated, less toxic ingredients - it is like the holy grail of batteries. It will ignite a revolution in everything from laptops and mobile phones to motor vehicles to renewables to the nature of our electric grid; the model train will evolve as well. It will be an exciting time to be involved in the hobby.
All of which is to say: Deadrail and RC model trails will become more prevalent, and they will likely run on 2-rail track!
