I have many analog locomotives but only a handful of Delta locomotives. Before I invest in any Delta controllers I have some questions. What would be better? A 6604 controller between an analog transformer and feeder track or a 66045 with the transformer function? I read that an analog locomotive will not work with the 66045? If that is true then will a 6604 interfere with the analog operation from an older controller to the track as well? I know that the Delta locs shouldn't be a problem on an analog layout. How can I run an analog locomotive at the same time as a Delta equipped one on the same track? By catenary and the Delta ones operate off the track or vise versa? One more none Digitally functioned question. On one track with catenary, is it possible to run eight different locomotives with one 6604 plus transformer feeding the track and one 6604 plus transformer pair feeding the catenary? Just seeing if you folks that have had these running around for years have any first hand experience with this. Just talking strickly Delta and analog mix here. Thank you.

Hi Roman,

Once you connect a 6604 or 66045 to the track, any analogue locos on the track will run at full speed, unless you keep them seperate by running them off the catenary as suggested by Per above.

My own solution was to have both delta and analogue feeding to the track through a switch, so that I could select which mode to operate in, either analogue or digital. I then introduced several isolated sections on the layout where I could park trains when not running. The idea is that when you want to run delta or digital you switch over, then you energise the sections of track with delta or digital locos on it, leaving the analogue locos in isolated sections. To run analogue locos you do the opposite.

A simpler way is to have two seperate tracks which are not linked, then you run one analogue and one digital/delta.

IMHO the 66045 is much better than a 6604. Better speed knob, all controls in one box, and you can switch the lights of digital locos (most Delta locos don't have digital functions that can be controlled).

You can run 4 locos with one delta controller via the track and simultaneously 4 other locos with another delta controller over the overhead wire.

Thank you for the info. It helps the slow of learning, me. I suspected some of it already but, of course, have no experience with it so it helps to affirm my suspicions on some of the points.

At this point, rather than going delta, I would consider trying to find a 6021 digital unit that is being liquidated. It could be one from a Start Set or one that is remaining in inventory. This would enable you to operate your delta loks and also any new digital loks that you acquire. At the same time, you can gradually convert older loks to digital and use them as well.
I like the idea of having a parallel radius using analog so that you can use your older trains as well until you make the complete conversion.
