The lack of ABC on most of my HOe loco's got me thinking... So here's a thought:

1. An isolated section at the end of every storage track, the loco will stop dead when it hits that part of the track

2. A MERG DCC stationary decoder with a 30 second pulse, connected to a relay

3. The relay switches the DCC power to the isolated section, enabling the loco to move off

This means I can select the track and when the loco arrives, it will stop dead, then when it is to move off again the track is selected, the dead section energised, and the loco moves off again!
