Steam & Excursion > SP 0-6-0 surprise

My plan is to spend Labor Day at home to catch up on so many unfinished projects. Well, some new projects I haven't started yet. They will be unfinished projects by the end of today. Going through a batch of SP steam locomotive photos I found this shot of 0-6-0 SP1010 taken by W.E. Miller at Bayshore Yard in San Francisco on New Year's Day in 1937. I can't recall exactly why I purchased this photo so many years ago, but I supposed it was (1) a SP steam locomotive, and (2) it was taken at one of my two favorite SP facilities.

While looking up the statistics in Diebert & Strapac's "SP Steam Locomotive Compendium" it suddenly occured to be why I may have purchased this photo in the first place. It later became 0-6-0T Bayshore Shop Switcher SPMW966 on 4/1/1937, of which myself, Martin Hansen and others have shared photos of before.

This was the second 0-6-0 asigned a number that was previously used by another SP 0-6-0. The history of 2nd SP1010 in this photo: ex-EP&SW #18, ex-EP&SW #408. Built by Alco-Schnectady in October 1907, and vacated 9/30/36. It was rebuilt to SMPW #966 on 4/1/37. Vacated at Bayshore 6/1958. Sold for scrap 4/7/60 to Luria Bros. South San Francisco. It was in a group of the last three steam locomotives to leave the Bayshore deadline. Here is 2nd SP1010, and her later resurrection as SPMW #966.

Wonder what happened to the stack in the first picture, looks a little worse for wear

There are exhaust splitters. This must be an exhaust stack splitter.

Here is the SP 1010 in better days - San Jose 1934.

What's an exhaust splitter? What does it do?

An exhaust split was a metal device that extended right above the stack which deflected the smoke and exhaust to both sides of the boiler. The idea was to reduce damage to tunnel and snowshed roofs by deflecting the pounding of the exhaust from exiting straight up.

Question on a mechanism. Below the cab at the back cab wall (fireman side) there is a cylinder of some kind with a shaft extending forward to a little shy of the rear driver. In the tank engine picture you can see this attaches to a lever that goes down under the fire pan. What is this mechanism? A grate shaker? Something else? How is it controlled?

It's not a grate shaker as the locomotive burned oil. My guess is it's part of the engine's independent brake system.

I asked that question some time ago, and yes, it is part of the independent brake system, an actuator.
