Locking your locomotive into a single operational state

T o select a single operational state for your Lionel locomotive (for example, forward only),
you can deactivate the Command reverse unit's sequencing function with the Command
reverse unit (PROG/RUN) switch.
Get your locomotive moving in the desired direction, then slow it down without stopping.
Set the Command reverse unit switch to PROG. Refer to Figure 2 for the location of the
switch. The locomotive is now "locked" into your chosen direction.
When you no longer want single-direction operation, just slide the Command reverse unit
switch back to RUN.
Your locomotive's reverse unit will "reset" to forward after any power interruption
Note!
lasting five seconds or longer, regardless of the original locked-out direction.
