Nostalgia & History > SP/T&NO, neeSA&AP 2-8-0'sDate: 02/05/05 21:29 SP/T&NO, neeSA&AP 2-8-0's Author: xtra1188w Even though the T&NO absorbed the SA&AP ( affectionally still called "the SAP" in its home environmens ) in about 1925, the SAP is still admired and referred to as a separate entity by most of the older railfans in Texas. I'm going to post three pictures of three different SAP consolidations here. Two of them still look purty much natural SAP, while has been SPized with a Vandy tender and etc.
Here is the first one, #870. I typed their vital data on the face of each image, so I won't repeat it here. I don't know whether too many people would call these little workhorses pretty, but they certainly do have character. Besides that, "beauty" is still in the eye of the beholder.

For those who didn't know but didn't care either, just don't read this far. The SAP was wholly a Texas Railroad. It looked roughly like it was built in a cross shape, when looking at a system map.

This was very representative of their stock frame depot design. Some depots were a little bigger, others might have been a little smaller, but just about all of them, including the HQ depot in San Antonio had a similar "family" look to them.
This particular depot was at Sinton, which was on the mainline to Corpus Christi. US 77 goes through Sinton. Con Date: 02/06/05 08:08 Re: SP/T&NO, neeSA&AP 2-8-0's Author: TonyJ Wonderful old SA&AP shots there Con. - Tony J.

It looks like they tried to make a piston valve engine out of a slide valve engine. Somebody smarter than myself will have to answer that question.

Slide valves do not work well on superheated steam, so piston valves were installed, either by replacing the entire cylinder block, or by just bolting a new valve chamber casting atop the old slide valve cylinder castings. Modification would also usually require changes to the valve gear, since slide valves were always outside admission and the replacement piston valves were most often inside admission, as evidenced on these engines by the steam pipes coming out of the smokebox into the top of the top of the valve chamber. These particular engines, however, have Alco cylinder relief valves on the front of the valve chambers, and the Walschaet valve gear on 878 appears to be set up for outside admission. I've never seen such a modification quite as grotesque as this one, however, and the grotesque valve chamber castings are probably to allow the space necessary for internal steam passages for outside admission.
