Different ways of reckoning IND and BMT |

Posted by Eric B on Thu Apr 21 18:11:10 2005, in response to Re: Photos of Stillwell Terminal's new facade, posted by David of Broadway on Wed Apr 20 07:09:19 2005. Structurally, the lines (and their stations) remain what they were constructed as. All four lines leading to CI are solidly BMT. Yet; 3 IND routes were extended over them over time. Two of the lines were connected to the BMT on both ends (CI and Dekalb). One of them saw continued BMT Broadway and Nassau line service. The other could still have BMT trains rerouted over it to CI terminal or yard. So these lines still retained their BMT association. The IND routes running over them were said to become BMT in the sections running over them. The car equipment also became a mix of BMT and IND. (this began to become irrelevant; as different cars were spread all around anyway, and beginning with R-42, new cars also spread around).The other line was connected only on one end (CI& the yard), with the BMT connection on the other end severed. So it became IND completely (even down to the signal chaining code; which went from BMT-C to an extended IND-B). However; the radio channel remained BMT. (it would have to change over somewhere anyway, so why bother changing the line for several stations?) Car equipment generally remained IND. Meanwhile; there was one or another BMT line extended over the Queens IND. This retained BMT designation and equipment; until it was truncated in Manhattan. Then, it took a north-orientation, with an IND-style EE designation, and was then considered IND. Equipment was then a mix, IIRC. Also, another BMT line was extended to the IND 6th Av. line, and retained a BMT designation, but was shortlived. Another BMT line had IND extended over it; but the BMT connection was a several mile long light rail only line, which was demolished. Completely isolated from the BMT; it became strictly IND, with even the radio lines converted. The chaining code remained BMT (K), however. The 7 is connected only to the BMT, so in the control center, which has a wall diagram for each division, it was included with the BMT, and so uses the B1 channel, and answers to the B1 Desk next to that map. Even Hagstrom maps revised it's designations during the Manhattan Bridge switches. They used to follow the structural definition of IND and BMT (except for Culver and Liberty, which became IND) with lines having different length dashes distinguishing each. Grand St. was drawn as BMT, and then it merged with the IND before Bway-Laf. Queens was IND. But then, at some point; they began showing Queens as both IND and BMT, with both lines next to each other. Then, when the B and D were moved over to Bway; they showed the double line on Bway. Grand St. was an isolated piece of BMT that still merged with the IND. Then, when they were moved back to 6th Av. with the Q; the double line was on 6th Av. to 57th, and then 21st. St. I was waiting to see what they would do for the 2001 changes, since the IND designations were not going back to Bway that time. But it was then that they did away with the old handdrawn maps, and replaced them with the new ADC style computer drawn maps, which use a line similar to the old IND line (with short dashes) for all subway lines. What I was wondering, was when the crew assignment was consolidated into the present North-Queen-South system. How long was IND/BMT maintained. I remember in the 90's; when I was learning more and more about the system (but not working for it yet) I had heard someone say the the Brighton was completely IND (both D and 6th Av. Q), then. IIRC, he may have been talking about the "personnel". Was it still divided like that that late? In one sense, you can look at South (Dist.5) as descending from BMT, because the CI and Dekalb hubs and lines between them were the bulk of the BMT, but with the B and D added to it. Queens (Dist.4) descends from IND, based entirely in the Queen line and Jamaica yard, with the R added to it. North (Dist.3) is basically the grouping of the unrelated lines from both divisions left over. (It would be connected with a C/M combo; but that is another currently ongoing discussion. Otherwuse; they are similar in that the C, J, L, and M remain 8 cars; and until the L getting the 143's; were always the dumping ground of the system. They also can be said to have a common hub in the ENY area; though once again; there is no physical connection there). Though the D used to be apart of the North I heard. I guess in a way the A, C and D as north could also be seen as descending from the IND; with the BMT East thrown in. So the IND was split into those two districts; while most of the BMT remained nearly intact as District 5 |
