A mixed manifest train hauled by an AC4400CW (CSX 161 leading) and an SD 40-2 (CSX 2802 trailing) is sauntering out of the Sand Patch Tunnel ready to put the dynamic brakes in set-up and start the descent down into Cumberland, MD.
Choo Choo, here comes the knowledge train! Curious as to why that sign (a speed limit marker) has 2 speeds (in mph) listed? The top number is for passenger trains and the bottom is for freight (or mixed) trains. This freight train will be authorized a maximum speed (unless further restricted by signals) of 30 mph. Speed limit increases take effect after the entire train has passed that sign. Speed limit decreases take effect immediately as the front of the train passes the sign.
This screenshot was taken by myself on PS5 playing Train Sim World 4. The route is Sand Patch Grade from Rockwood, PA to Cumberland, MD. All locomotives shown are in the original liveries provide in the game, no custom content to credit.
