 9/9/24 - Stream appaers to be having internet connctivity issues....Hopefully it will be resolved soon.

Welcome to the Lancaster, CA Area Stream which brings you the east side of Tehachapi coverage, including the mountain trackage, switching activities in and around Mojave, and Branch Line action on the Searles  and Lone Pine Branches. .

Detector Notes:

This video depicts the rather unique joint operations of the UP Searles Local and the Trona Railroad. Big power is the rule of the day because the heavy ore trains demand it. The Trona uses all Ex SP and UP 6 axle EMD power - it may not be freshly painted but it still knows how to move the tonnage. The Searles Local can be heard getting Track Warrant Control from the UP dispatcher incharge of the Tehachapi area traffic on this stream. Besure and listen for it.

This Annotated Google Map shows the Major Sidings on the Tehachapi Hill 

Dragging Equipment and Hot box/Wide Load detectors will be added in the future.

Hover over the Marker to see details about what it represents. 

Don't forget you can zoom in/out and pan-scroll the map view 

Also change to satellite view using the google gadgets on the map itself

Unfortunately Google has changed their policy with respect to

free-sourcing maps on web-sites, so we'll leave the crippled map up for now.

Below is a computer simulated graphical plot of maximum possible receiver coverage using the Longley-Rice Prediction Method adjusted for a very weak receive signal (.2uV for 20dB quieting) which best approximates some of the weakest signals heard from the most common distant locations.

Note: it is not unusual to hear signals outside of the red zone depicted, but those are due to non line-of-sight propagation modes which are variable and unpredictable due to weather and various secondary propagation modes such as RF Ducting, Knife-edge , and E skip (ionospheric bounce).
