Fitting
track-powered interior lighting to the LGB RhB baggage van
(can be
adapted to other vehicles and brands)
LGB
introduced a 4-wheel Rhatische Bahn (RhB) baggage van as part of
their 2004 range. The model is based upon a prototype that was
rebuilt on old 4-wheel coach chassis, and offers modellers of
the RhB a cheaper alternative to the large bogie van. The van is
currently available in red, and in blue/white “Alpine Classic”
livery as a limited-run model. I bought the Alpine Classic
mainly as I prefer the colour scheme!
When I
received my model in March 2005, I was impressed with the detail
and standard of finish, however, I was less than impressed with
the plastic wheels, which tend to attract dirt and also neither
look nor sound as good as metal wheels. Considering Bachmann is
able to fit metal wheels to models costing a fraction of this, I
feel LGB should be able to. I decided to solve this problem by
fitting a set of LGB’s ball-bearing wheel sets, as these also
reduce drag (which can be considerable on a long-wheelbase
vehicle running on tight curves). As these wheel sets include
power pickups I also decided to fit interior lighting to the
model. As I’ve also used these parts on other coaches over the
past few months I’ve included some advice based on these
installations.
The parts:

Step one:
remove the roof. It should simply unclip, though persuading it
to do so can be tricky. Try gently flexing the sides of the
vehicle out if it’s unwilling to move. Just don’t use either
excessive force or tools, as spare parts for these models are
expensive!
Step two:
open your lighting kit(s). For this installation I’ll need some
extra 2-core wire (automotive speaker cabling), as I need to
wire the two units together and hook them up to the wheels. To
do this, I start by unsoldering the factory wires, then measure
three lengths of the new wire. One runs between the units, the
other two run down through the holes in the floor to the wheel
sets. When happy with the length, solder them in place, making
sure you have the same polarity throughout to avoid
short-circuits. You may also at this point wish to fit the
little spade connectors provided with the ball-bearing wheels to
the other ends of the power wires, as following this course
enables you to keep the soldering iron clear of the plastic
rather than having to carry out delicate work later on.

Keep the
spare sections of wire with the plugs on – you can use these to
make up “through cabling” for vans etc running in “wired”
passenger trains. Likewise you may wish to keep these cables
fitted to the lighting unit – I have a Sachsen 4-wheel coach
fitted with metal wheels and interior lighting that operates as
extra pickups for my Stainz 0-4-0, connected via the socket on
the back of the cab. In this situation the correct polarity is
even more important, as not only must it be correct through the
vehicle, it must also match the loco. In this case I’m not
keeping the wires as they would be rather unsightly on a model
such as this, and also wouldn’t be needed to power other
lighting – all the LGB RhB coaches are fitted with lighting and
track pickups
Step
three: the fun part. Routing the power feed wires in such a way
as to avoid them being visible from the outside. I pre-bent them
to follow the end walls and floor of the vehicle before leaving
via the pre-drilled holes in the floor. These holes are not
always present, though there are guide markings – the
aforementioned Sachsen coach was not pre-drilled but using the
markings made for a simple modification. Once the wires are in
place, you can clip the roof back on.
Step four:
the ball-bearing wheels are a simple clip-in replacement for the
originals, and the spade connectors simply push on as shown
here. Check that you have the correct polarity at this point to
avoid potential damage later, and the work is complete.
