Thanks for noting me Stewart. I was doing design work on the brake system- specifically designing foundation brake gear for the J&S rebuild trucks and future trucks. The lever arms and reach rods must apply the correct force to the brake beams in order to avoid sliding wheels while still getting effective braking action. These levers had been designed for externally applied brake force, but we are now adopting the Eames Brake Co practice of truck-mounted vacuum pots, so the forces and mechanical systems which support them must be verified. Remarkably- nearly the entire J&S truck brake system works as is with little modification while accommodating the vacuum pots that Jonathan had perfected.
We are developing detailed sub-system design in order to perform an engineering group design analysis and verification. We have been in communication with FRA representatives on this topic and have a desire to design and install this brake system in a manner consistent with the industry standard. Once these documents are complete, reviewed and finally revised, our complete package will enable any sub part of the system to be implemented with clarity and predictability.
Loco 9 and train looked and sounded great coming in at twilight this evening.
Thanks
