AFAIK back in the day there were many more changes that impacted individual lines rather than attempting to "save up" extensive changes until the next general pick.And some changes were seasonal. Many Southern Division BMT changes came about for the summer. |

On occasion, the TA would conduct “line picks” which would only impact crews working within a specific section. When the Myrtle Av El shut down in 1969, there was a line pick for there M line which required crews formerly working the Myrtle Av el to pick runs on the M line. Their respective days off did’’t change but the actual runs worked by the crews did. Additionally, the crews working RDO relief jobs in the Eastern Division now had to work the runs as repicked by the crews they were replacing on those days. Some times, a line pick might affect several lines within a section which might change without affecting the rest of the division. An adjustment to the Bkln service pattern on the F might affect only runs in the Queens section of the IND but not the Concourse or Manhattan North sections. |

Were their individual line timetables before January 1976? The oldest one I've seen was a D schedule that showed effective date January-March 1976.Has there been any section/division changes from that time ago? |

I don’’t recall any public ones prior to 1976 which is the year I went into the schedule office but there were certainly internal timetables. I do recall that sometime in the mid 1950s, the TA published a few timetables although I had heard that they were only for the midnight hours and even though I saw a few, I didn’t really study them carefully. |

I think there were mini-picks where anyone could pick onto these runs if they felt they were better than what they had. For example, there were people on work runs (IIRC, no more than two days out of five on the same run) and the extra list. |

For an 8-10 minute headway, I would sometimes use a timetable to time my arrival, assuming I could control my arrival time. I might aim to arrive 2 minutes before the scheduled arrival. I'd definitely avoid arriving 1 minute late. |

Sometimes if changes were minimal enough, a supplement schedule would be issued and the runs would remain the same with the appropriate departure and arrival times for the runs without any pick. |

Posted by BusRider on Wed Aug 24 19:09:12 2016, in response to Re: Old Timetables, posted by randyo on Wed Aug 24 16:17:44 2016. When creating timetables is there a significant difference when determining running time for a local trip versus express on the same line? Considering the various speed limits or timers, individual motormen way of operation, and the time it takes to switch tracks/merge.Reflecting on the 1976 D train schedule: At Kings Highway (arrival times exaggerated) Local would arrive at 3:02pm Express would arrive at 3:00pm Both trains would arrive at Sheepshead Bay at 3:06pm and 3:03pm respectively. Express trains skipping Avenue U and Neck Road. It appears the saving of three minutes for a two minute departure difference. |

According to the math, the exp running time is 3 min and the lcl running time is 4 min a difference of one min which is about right considering the rule of running time difference is a half a minute additional per station for lcl running time vs express running time. A half minute each for Ave U and Neck Rd equals a full minute which is exactly the difference between lcl and exp running times between K/Hwy and Sheepshead Bay. |

It appears establishing running time, stations are typically one to two minutes apart. Has distance between stations or accel/deacceleration calculations ever been used to determine running time? Or calculating the signal time (# of signals in between stations and calculating their cycle time (red, yellow, green))?Being that dwell time at stations is the crucial factor in causing delays. |
