Hello again Randy-O !!What you obviously and understandably forgot about was the fact that a 5 or 6 car train of even Wooden framed (not withstanding the later 1908-10 steel framed IRT EL cars) IRT EL Gate Cars or MUDC EL Cars, loaded with non rush hour passengers and even more so with rush hour crowd passengers, is FAR HEAVIER than EACH of a few very short, and time-spaced very far apart, trains of EMPTY composites running in a convoy of one-time transfer moves on the 9th Avenue EL on the center track...in off peak hours. I can't remember exactly now, but I seem to remember the witness (a noted railway historian of the time) of these few moves back then, stating the few consists were 4 cars in length...but don't quote me. The use of the Composites operating EMPTY on the center track thus spread out the weight factor evenly across the structure and supporting pairs of EL columns. And specifically, it was the certain portions of the EL structure BELOW W. 60th Street which had some of the very oldest and weaker EL Columns and structural sections and strict weight restrictions. The 9th Ave. EL structure from 61st Street north, thru the West 80's, was equivalent to the 3rd Avenue EL Line's "reinforced tops" TRENTON style columns-supported structure -- and more specifically, in the high West 90's Harlem section thru to the W.155th Street Station, the 9th Ave. EL structure was built to 2nd Ave EL stronger Standards and appearance using heavier lattice spans and the heavier solid round "Phoenix" EL Columns. So the few far spaced apart "transfer consists" of 3 or 4 composite cars running empty would not have adversely affected the 9th Ave Structures --- however the Composites could NOT operate on ANY tracks on that line WITH ANY NORMAL or ANY Rush Hour PASSENGER LOADS for any reason - mainly because of the below W. 60th Street 1875-77 built and added-on--to piece-meal segments of unimproved structures. As especially not in any daily regular express service. The same held true for the 3rd Ave EL South ferry Branch (structures over Pearl Street and Front Street) So that is the reason that route was chosen to transfer those relatively few Composites to the Polo Grounds Line -- and done only within a few days before the 9th Ave. EL line shut down permanently. PS: Always enjoy conversing and swapping history with you ! regards - Joe F |
