build or buy a corded throttle for the straight run. Figure 7 illus-
trates my proposed control panel layout, with the location of
track rail insulators defining block limits, and the style of toggle
switches to be used. To start, only one DPDT center-off switch is
required, and that is to control the polarity of the reversing sec-
tion of the track wye. The other switches may be added as addi-
tional throttles become available. All toggle switches might be
DPDT center-off switches but all stub tracks require only a SPST
on-off switch. Only one rail gapped, and more storage blocks
than the two shown per stub will be desired. Wiring is all con-
ventional, and space here does not permit covering it in detail.
Although I am not able to duplicate the IRM, I believe it is desir-
able to try to understand it to a reasonable level, in order to
make my layout appearance and operation believable. Even in
N scale, the loop would require the layout table to be twice the
width and length, and the five-mile run would require 165 real
feet. I continually refer to the IRM website,
where they
