Hey all, looking to operate my SP style dual semaphores. I've seen the tech out their by tam valley etc but my problem is, is that I have dual dc analog motors connected to operate my signals. Is their a simple diy cheap way of operating them while the block is occupied? I was thinking of an photo cell sensor so when its triggered at point A arm moves and does not go back until the next point is reached. Any ideas? Thanks!

The topic of grain operations on modern regional railroads recently came up on the Yahoo Proto-Layouts list.  I thought I'd post my reply here as well in case the information I compiled is helpful to others.  My information was gathered with regard to the Iowa Interstate, but the principles should apply elsewhere.

I would like to eliminate the reserves that are listed at various locations.  I can not get certain trains to move cars because the reserve for that spur has a large number listed in the reserve column.

 I tried resetting the car moves to zero with no success.  I reviewed the JMRI Operations manual.  I tried going on the Yahoo users group but that was an exercise in frustration.

There must be a simple solution but it eludes me.

Any help would be greatly appreciated....Ken

As with everything on a model railroad layout, after I thought I was finished I had an inspriation as to how to connect a second RRampMeter to the other booster. And had been working on the train elevator and came up with a way to integrate its control with the panel.
