I attended a radio control clinic at the March Meet. Several interesting charts
diagraming the development of our hobby for the last hundred plus years.
All used power from the wall, wires to the transformer, wire to switches
and on to the track from which the locomotive drew its power. Whether
two or three rail, whether throttle or remote control - that is how it was
done.
January of 2013, the lithium batteries got smaller. The demonstration used
a remote control to signal the steam engines (2) on a non-powered test
track. As an engine was running, a steel file was placed across the track.
No short as there is no electricity in the track. I asked if two rail engines
could then be run on three rail tubular track. The moderator then lifted
the steam engine and tender off the test track and placed it on the table
cloth. Now that he had everyone's attention, he ran the unit on the
table cloth. It can be run on wood, plastic, etc. This may revolutionize
our hobby and may warrant an article in OGR.
A 'charge' lasts about five hours which is more than enough for any
engine in an operating session. The recharge port was in whatever
that box under a tender is called but can be placed anywhere including
the fuel and water intakes on the tender.
For two rail operation, this means no more reverse looping wiring.
For both two and three rail operations, it means no track wiring,
no track cleaning, no dead spots at turnouts. None of those electrical
exist, very similar to the 1:1 scale as the
power now comes from the locomotive (actually the tender).
