LCC - Best for Layout Control

   By Jeff Gerow

Considering all the options for controlling Jerry McDonald's staging yard switching- including pushbutton as well as dispatcher control -I found that LCC was the best available option. How LCC works, what it can do and its advantages over alternatives will be discussed. I will show the programming that allows individual tracks in Jerry's staging yard to be connected to the main (using multiple turnouts). This programming is the basis of LCC control and leads to not only such things as self-contained ABS signalling (with no dedicated PC to make it work), but also JMRI-enabled dispatching. I'll end with a discussion of what's available now that already allows robust LCC capability and share recent announcements from manufacturers creating exciting new directions for this technology.

A TrainTech Recipe: Arduinos, CMR/I, and JMRI

     By Jerry Grochow

    Arduino micro-controllers can be used to control turnouts and accessories on your layout (among other things), regardless of whether you’re using DC or DCC. When connected to JMRI (Java Model Railroad Interface software control system) on your personal computer, via a CMRI network (Bruce Chubb’s Computer/Model Railroad Interface), you’ve got a winning yet inexpensive combination! This clinic, for the beginning-to-intermediate “traintech” user, shows how to put things together for train movement control of crossing signals, direction and speed display, and integration with other automation via JMRI.

Advanced Topics in DCC Speed Matching

    By Mark Granville

    This seminar will discuss various challenges and frustrations that come up when speed matching locomotives that have decoders from different manufacturers. Examples will be presented, causes will be discussed, and solutions will be offered. A short review of speed matching procedures will be given, but it will be assumed that the attendee already has some familiarity with the concept of DCC speed matching.


Lineside Signals

    By James VanBokkelen

    Slide show about engineering, designing and building automatic block and interlocking signals for my DC/DCC layout.  My signals don't require a computer, can be installed location by location and are debugged with a voltmeter. Includes selection and use of commercial components, how to implement basic ABS and interlocking logic, communication between signal locations and discussion of modeling searchlight mast and dwarf signals following B&M/MEC practice and rule books.
