This is my prototype reverser in
my (very) short 'loop'. The arrows indicate cuts in the tracks.
The circuit board contains: yellow brick (dual latching relay), 4 signal
diodes (top right), 4 rectifier diodes (above and below the relay), two
snubber diodes cross the colis of the relay, two transistors (just to the
right of the relay), three resistors, and three capacitors. |
This shows an example of the reversing
section in a simple layout. Normally, the reversing section should
be long enough to hold an entire train length.
By the way, this circuit works for
DC engines, but as they try to exit, they reverse direction (and reversing
again at the opposite end). To get them to exit, you have to manually
reverse their direction a second time just after the first reverse.
This isn't very prototypical - a little hiccough on the way out.
As a bonus, because of this side
effect, this circuit would also make a good reversing circuit, for say
a diorama, in which you wanted an DC engine to shunt back and forth. |
