Some facts: the original boiler is in terrible shape. There is enough thickness reduction on it, that it would only be certified to 180PSI. That means it could only produce enough steam for 40MPH operation. Who wants that? And it's life as an operating steamer would be limited. With a new welded boiler, it can steam at full pressure, run at 80MPH, put a full train. and with management of water, it can run nearly forever. Adding the Timken roller bearing will eliminate another major issue with this engine, reduce maintenance, and improve operational performance. Neither change will be readily obvious when the engine is complete. Millions have been squandered on restoration of this engine over the past 30 plus years, and it is only marginally closer to being back under steam. In my view, this is the right way to bring her back, for now and for future generations. Been watching this project for many years - Bennett is a hero in my mind for pushing this in a positive direction
As much as I'm intrigued by the T1 trust, they have a long long way before they have an operational engine, and their boiler will also be welded. So let's get the K4 back on line and run it wherever it can.
