With the Riverdale receiver it is
possible to read the boiler pressure on your transmitter using
telemetry. This is very comfortable when you cannot read the pressure
gauge for a long period of time. On top of that – when selecting
AUTO mode - the Riverdale receiver will open and close the damper
automatically at a certain preprogrammed pressure.
And should you want it, the receiver could control front, back and cab lamps.
The Riverdale receiver does work with any Amy, Elke, Irene and Darjeeling 'B' Riverdale boiler.
A temperature sensitive resistor is fitted under a boiler band. The
temperature of the boiler equals the temperature of the steam inside
the boiler which equals pressure (120°C=15psi; 133°C=29psi;
144°C=44psi; 152°C=58psi). A very little microprocessor is
programmed to calculate the pressure and – in AUTO mode - to open
and close the damper automatically.
The little microprocessor Printed Circuit Board together with a
Reely/Flysky receiver is
built into the Riverdale receiver and fitted with 2 connection blocks.
The connection block for servos,
batteries and temperature sensitive resistor exits in line with the casing. The second sits on top of
the Riverdale receiver for connecting front, back and cab lamps.
Because the connectors are in line with the casing the Riverdale
receiver is very small, even with all connectors connected. So it fits
optimally in all Riverdale
Controlling the Riverdale receiver with right up/down stick
DOWN: activates whistle and turns on AUTO mode.
UP (short): closes damper and turns off AUTO mode.
UP: holds the damper in any selected position (HOLD mode). UP in AUTO mode toggles lamps.
UP until transmitter displays 0.6 volts (takes 5sec): brings you in PROGRAM mode.
To check the receiver batteries, the first 6 seconds after turning on the
receiver its battery voltage is displayed instead of steam pressure.
A standard telemetry combo is used, meaning that the display is in
Volts. While calibration is in Psi, 40 Psi for example is
displayed as 4.0V. Minimal pressure displayed is 8 Psi (0.8V).

Riverdale receiver fitted in Amy: temperature sensitive resistor connected to T
connection. Servos connected to CH2 , CH3 and CH4. Lamps not yet connected.
For the Riverdale receiver you need a Flysky
FS-i6 transmitter. This transmitter can control upto 20 models and has
a 3 position switch what is very convenient for the reverser servo.
You can opt to order this transmitter yourselves. More info here
Fitting lamps in locos is described here
The pressure feedback and the automated damper allow for slower
running. For full potential - depending on your loco and lay-out - a
smaller exhaust nozzle could be fitted. In that case fit a 1.2mm nozzle instead
of the normal 1.3mm
nozzle. And with a Slomo fitted - when running with a 1.0mm nozzle - fit
The Riverdale receiver is designed specially for Riverdale boilers only
and is produced in small quantities by Riverdale Locomotives.
