Western Railroad Discussion > UP's LSF-51 Charging up the Quint St. Ramp

UP's Warm Springs, CA-based Mission Bay Local brought in 60+ contaminated dirt empties
into South San Francisco last night which gave a clue that the SSF-based LSF-51 would
today make a run up to San Francisco's Pier 96 to swap empties for some dirty dirt loads.
They brought about 30 of those empties up to the pier today.

They returned south with a train of about 50(an estimate) dirt loads and are seen today 
at 13:40 with the UP1088-1017 for power making their run up the ramp leading from the
Quint Street Industrial Lead to Caltrain main one.

I'm estimating this very short grade at about 3% and with only ten or so cars on the ramp
at a time its just a matter of the power making a quick run at the "hill" with its 6500 
ton train.

The third crewmember on the 51 job follows along by truck--mainly to work the hand throw
electric lock switch at m.p. 2.9 leading to and from the Quint St. Lead.  The crew uses
161.460 as a switching channel at SSF and Pier 96.

The dirt is a pretty dense commodity and the loads max out on weight before the cars meet
their cubic capacity.  Consigned to the disposal site on the ex-DRGW Sunnyside Branch in
Utah.

Nice photo coverage. In the thrid photo, the pick-up truck is parked on the ROW of an industrial leed that used to serve numeous industries
west of the main including the American Smelting & Refining Mill around a mile north of this location.

Great coverage and nice images!

The truck in the third photo is sitting on what was track 300 of SP San Francisco SPINS Zone 3.

Ok so what does SPINS Zones stand for? On the Santa Fe they were CLIC charts " Car Location Inventory Control" on KCS they were SLIC charts (Spot Location Inventory Chart) and I'm sure there were others. Ah ha, a little more info, not a UP name but an SP name,Southern Pacific Industrial Numbering System "SPINS" Books  thanks Google. The Union Pacific calls them ZTS (Zone-Track-Spot) maps. Answered my own question, thanks.
