Yes, the "D" means it had an extra door open position. Andthere were further variants, such as the inclusion of a door selector valve on the brake valve body casting, or a treadle set position. Dave G. from OERM once distributed at ARM his list of every known "M" series brake valve from M-1 to ME43 and it was about 100 pages. |

A way to indicate what you want would be a new style of electronic side sign. A Large LCD TV-style Sign with multiple lines of information. The color bullet or diamond would be displayed in the upper left. The originating station next to it in a smaller font. The destination would be in the center. The lines traveled would be at the bottom. The Manhattan trunk line (which generates the route bullet color) would also be back lit with the color.Here's what it would look like, textually. (J) Broad St. to Jamaica Center Parsons/Archer via Nassau St. Lcl Bkln Bwy Exp Jamaica Skip/Stop Archer Lcl As the train travels its route, the "used up" lines would disappear. Nassau St between Essex and Marcy; Broadway between Broadway Junction and Alabama; Jamaica between 121st and Sutphin. In the reverse it would look like this. (PM rush) (J) Jamaica Center Parsons/Archer to Broad St. via Archer Lcl Jamaica Lcl Bkln Bwy Lcl Nassau St Lcl |

However, the descriptive post has one slight error SMEE is the acronym for (S)traight air (M)otor car (E)mergency feature (E)lectric. the final "E" in WABCO and older NYAB brake acronyms always stands for electric. Some transit properties had similar brake systems which lacked the electric feature and were designated simply "SME" and had similar features to the SMEE but without the electro pneumatic feature since they were designed for single car or short 2 or 3 car operation such as street railways or interurbans. Other examples of straight pneumatic vs their respective corresponding electro pneumatic brake systems include AMU and AMUE, AML and AMLE etc. |
