    After making a turn to Galloway, MO GP7 SLSF 582 has just passed Pacific Street Jct.

    It is on the 43 track as it makes it way back to Springfield / Kansas Avenue/ West Yard.

    Photograph dated March 1975.

    Karl, or anyone else,

    I just want to verify I have the track labeling correct here.

    My understanding is that 43 track is the westbound connection between the Middle Belt and the mainline in the North Yard area.

    Is that correct?

    I am trying to reconcile that label with a 1998 BNSF track chart for the Ozark Branch that shows the Pine Street Junction and MK Junction area and labels that drawing "43 Track, MO".

    This area includes the Missouri Pacific (MP) / Union Pacific (UP) / Missouri And Northern Arkansas ( MNA) crossing connection.

    Other track charts in the 1998 collection do label the connection at north yard as 43 Track.

    Paul,

    I started the attached document earlier this year, but did not finish it.

    Here is a look at the Eastern Junction, Old East Belt, Pacific Street Junction area. Like it did with the MK Junction Area, during the mid-1970s the Frisco rationalized the track and signal arrangement at Eastern Junction.

    In doing so it created "true" double track between the New East Belt and Springfield / Kansas Avenue / West Yard.

    Thanks Karl!

    Incidentally, there was a picture showing one of those spring switch indicators posted to the Frisco Archives earlier this year:

    Though that was on the other side of the Anheuser Busch elevator.

    Edit 2/27/2024: The referenced Frisco Archive photograph shows a switch point position indicator. This was a powered turnout controlled by the yardmaster from the Springfield Yard tower atop the yard office building.

    These turnouts were controlled by the yardmaster to help expedite locomotive and train movements on the east end of the yard. Through these turnouts the yardmaster controlled locomotive movements to and from the service tracks facility and the south long tracks. In and out bound trains could also be routed to the north or south receiving and departure long tracks.

    By powering these turnouts trains could be expedited through the area. A crew member or hostler did not need to stop movements to line or reline the turnouts. Further, the position of the turnout, normal green or reversed yellow, was visible from a greater distance.

    The turnout in the photograph was not a spring switch.
