Nice to see PROMONTORY POINT (nee LOBLOLLY PINE IIRC) Running again.
Had a chance to chat with who I think was the owner last week while we were running around the car and spotting it. Complimented him on how well things were working. Being an engineer I like when things stop, some of the varnish fleet can be questionable at times. Conductor liked that the pins dropped on either end of the car and the hand brake held. Again in dealing with private varnish you just never know.
You may be aware that Amtrak certified private cars are subject to an annual inspection. The inspection covers many things, and braking/stopping functions (single car air test, and hand brake apply/release test) are part of the annual inspection. I have always believed that many PV's have had their braking pressure adjusted to use a lighter force (for example --- a J16 relay valve on 26C or 26CDW air brake system) when braking. That seems to reduce problems (such as shelling and spalling) with wheel sets.
When I operated 800708 MOUNT VERNON (now renamed PACIFIC ISLAND by the new owner), I never had a problem with handbrake application, but at times I had problems getting a full release on my handbrake. I learned that it released properly after it had been fully applied. However, a partial setting of the handbrake would hold the car in position, but it might not allow a full release. Thus I would reapply it fully, cranking down all the way, then I would pull the release handle and get a complete release.
