Is it my eyes ...

Is it my eyes or is the track plan for this article missing the complexity that seems to exist at the Portland Union station (Figure 1). I see several switch points in the camera shot, but only one or two in the track plan for this part of the layout.

OWN&R Co. Digitrax ABS & CTC Signalling Question

Hi.  I'm currently building an N scale layout with Digitrax equipment.  I plan to use JMRI for signalling and block detection using BDL-168s, etc.  In the article, Kent said that he was able to switch between ABS & CTC operation, and these in turn (naturally) changed the meaning of the signal aspects, etc.

Could you please share details of how this was implemented (including wiring implications)?  This might be a great follow-up article also.

(On a related note, there is a great series on signal planning in the LD-SIG newsletter.)

Thanks,

- Neil
