"Model Electronic Railway Group"
The group exists to foster an interest in the use of electronics in the control and operation of model railways.
More
information can be found in the Group's
main
pages.
These pages are a resource area for projects members are working on or
have completed and wished to make publicly available. Some of
these projects have resulted in MERG kits but nothing on these pages
should be taken as definative information about the kits, members
should check the kit pages for up to date information on the kits.

Remote Data Display
Gordon Hopkins has designed a display system to help operators of
layouts with
sequenced timetables keep track of their activities. Displays
for
several operators
can be attached, all controlled from one position. An
Acknowledgement facility is
included to allow operator feedback. Details of operation are
given in Technical
Bulletin G16-25, but some additional documents are available
here
to assist in
construction.

Potential Controller
11/6/99 (.pdf
added 7/7/99)
This
controller by
Chris Stanforth provides for single knob control and, of course the
split potential system
is particularly good for those wanting several controllers on a common
return wiring
system.
