HotShot™ Trackside Speedometers

Engine 6308 Thunders By

A rival UP crew stops to enjoy the show as Burlington Engine No. 6308 thunders by on the Colorado & Southern main line. In 1958, the pounding drivers and flashing side rods of a steam locomotive have become a rare sight.

Does your way freight engineer blow down the main line like a hot shot intermodal? Will that pokey Limited engineer be late again? Give your train crews the "guidance" they need to run at prototypical speeds, or see who can set a new record for that crack passenger train!

The HotShot™ Trackside Speedometer displays the scale speed of each passing train — and just like a highway speed trap, it sets off an alarm to catch another speed demon in the act.

And with a touch of a button, see how fast that last train was going, the high speed record for this session and over the lifetime of your railroad, and much more.
