Posted by randyo on Wed Nov 18 16:42:17 2009, in response to SMEE (Re: Questions from the eager & curious), posted by straphanger9 on Wed Nov 18 02:44:54 2009. One slight correction. In the acronym SMEE, The first "E" stands for "emergency" and the last "E" stands for "electric" or "electropneumatic." If you research the various other brake systems, you will note that on the brake systems that are electropneumatic, the last letter in the acronym is always the "E." There actually is a SME system which operates almost identically to the SMEE but without the electropneumatic feature. That system was used on many streetcars and interurbans although prior to the development of the self lapping brake valve in the 1930s, the straight air pressure had to be applied by fanning the brake handle between service and lap positions similar to the AMUE and other reduction brake systems. The streetcars and interurban cars which used the SME system with which most railfans would probably be familiar are the P & W Red Arrow Bullet cars, BMT 6000 and 8000 series streetcars to name a few. |
