Model Railroader – September 2019

I simply waved the included Rapido
Lighter (essentially a magnet on a plastic
stick) over the front of the car.


DCC operation. The performance chart
above is for a single car. Both 191 and
192 achieved identical results and accel-
erated smoothly to scale 83 mph, which
is close to the prototype’s top speed.
After programming both cars’
addresses to their specific locomotive
number, I advanced consisted them to
run back to back, just like their proto-
types. The models ran smoothly without
any additional speed matching required.
The consist speeds were identical to
those of the single-car tests.
The printed instruction manual
included with the set lists some DCC
programming tips. For a more extensive
decoder guide as well as links to free
LokProgrammer software, visit the ESU
website at http://www.esu.eu/en.
Note that there is no drawbar pull test
data. The Rapido Budd car mechanism
isn’t designed to pull an unpowered car,
and doing so will void the manufactur-
er’s warranty.


DCC sound and light. Pressing F8
started the diesel engine sounds. In addi-
tion to the horn and bell, other user-
triggered sound effects include a slow
and fast grade crossing signal. The head-
lights, marker lights, and door-mounted
Gyralight are controlled by individual
function buttons.
The overall volume and the volume
level of each sound effect can be adjusted
via CVs. All the functions can also be
mapped to any available throttle key.
Two of my favorite features are the
function button controlled brake (F4)
and straight to 4 (F3). The latter


simulates the prototypical practice of the
engineer putting the engine into notch 4
(Budd cars had only 4 notches) so that it
would accelerate quickly.

DC operation. The instructions warn
against running the sound-equipped
Budd car using older power packs that
are prone to voltage spikes, as this could
destroy the model’s electronics. For our
DC tests, I ran the model with both an
MRC Tech 4 and Bachmann power pack
without any problems.
As the charts above show, the model
accelerated smoothly on our DC test
track. The model has some built-in
momentum, which I thought made oper-
ation more realistic.
The Budd cars also ran well as a pair
throughout the voltage range and were
perfectly speed matched out of the box.
In DC, sound effects are limited to
the diesel engine. Both the headlights
and marker lights operate automatically
according to the Budd car’s direction of
travel. Note that in paired operation
both cars’ markers will be illuminated,
which isn’t prototypical.
As of this writing the Rapido Trains
RDCs are sold out at the manufacturer,
but they are still available at online and
brick-and-mortar retailers. Whether you
model the Santa Fe or are looking for a
Budd Car in another road name, the
Rapido Trains RDCs are definitely worth
seeking out. – Dana Kawala, senior editor
