DC SHUTTLE WITH STATION STOP

AND ACCELERATION SAS2-BR

The BLOCKsignalling SAS2-BR is a self-contained DC throttle, designed to operate
a single loco along a section of track. Upon reaching the end of the track, the loco
will decelerate to a standstill, wait for a period, then accelerate in reverse. It will run
to the other end of the track and then decelerate to a standstill, wait again, and then
accelerate off forwards.



Runs a DC equipped loco back and forth along a single section of track



Optional station stop function brings the train to rest at a station



Realistic acceleration and deceleration



Quick and easy to connect and set-up

For a long while simple shuttles have been available to model rail enthusiasts to
operate DC locos back and forth along a single section of track. We had wanted to
add further realism by controlling acceleration and deceleration, allowing the option
