When last summer
I bought that cart F
of the ACME
I said in the video
that purchase
it was carried out
because on that wagon
I wanted to achieve
a special prototype
I'm talking about the
VRE tank
or test wagon rec
what is that?
In 1948
an engineer of the state railways
he decided to take a cart F with a sentry box
install a pantograph on it
and use it like
mobile column to provide the REC to the carriages
in the absence of a locomotive
now this choice
that today may seem crazy
at the time it was motivated
from the fact that the columns
that supply electricity
to the carriages
they were not widespread
today in stores
and in the workshops
including the ferry that leads to Sicily
are present
of electrical outlets
of the columns
where there is a particular attack
with whom
it can be provided
electricity to the cars
at the time no
they were also the years of transition
between steam heating
which provided for absorption
of steam from the locomotive
or from a steam generator cart
to electric heating
to make the change
we should
repaint the wagon
mount a pantograph
insert the new Decals
besides I want to make it
a functional project
therefore the pantograph will be electrically
connected to conductive hooks
first we proceed with disassembling the car
in several parts
that is, the central cash desk
the sentry box
and the various carts
this because it will favor us
the painting of the whole complex
the sentry box can be noticed
which has some cracks
probably
necessary to change air
inside and allow
to the brakeman to survive
in this case
the sentry box will no longer be needed
so those cracks must be closed
to close them
I used the same trick
used on the carriage Try Hooks
I cut a square piece
of a transparent plastic bag
and I glued it there
this because
once everything is painted
that sachet will become gray
and will provide a surface
flat, smooth
to give the closing effect
on the central cash desk instead
I tried to reproduce the riveting
because inside
in the real prototype
there is a partition wall
to make riveting
I used a small brush and some drops of glue
that I tried to line up vertically
the effect did not come too well
because some are bigger than the others
but it did not come too bad either
a particular detail
it's a case
a counter
present on the side opposite the sentry box
where there are electrical connections
in fact it will have a Decals written
"attention 3000 V"
that can be achieved
with a piece of plasticard
it will be a counter
that we're going to do
I did it with a file
and then it will be glued to the wall
another important aspect
that the Test Wagon REC
to supply energy to the compressors
holding on the pantograph
or that allow
or which may allow the pantograph to stand up
has batteries
batteries that obviously are not present
in the normal F carriage
I have recycled batteries
from Corbellini coaches of the Hachette
that were sold
with additional batteries
I removed all the supporting part behind it
taking only the mold in front of it
where is the battery pack
I then closed the sides
with a piece of plasticard and normal paper
filled all with vinyl glue
that gives weight
be compact to the whole
and then I painted with black
on the roof obviously the pantograph must be placed
the pantograph needs a flat surface
the roof is sloping
so to do this
they used supports
to "U"
metal
that allow the pantograph
to be put in plan
I did not reproduce the U perfectly
because
make the U with the plasticard
you must be very good otherwise it will break
I left
a full section
it is not realistic
but it's a license I can afford
because I only see it
there are reproductions of this wagon
made much better
where these profiles are shown
the pantograph is fixed with a screw
whose hole was made in the original roof
and also since I bought a pantograph
which is sold as a spare
he also had insulators
I cut the underside of the insulators
to make them smooth
I glued them to the pantograph
to make everything more manageable
and so the overall effect is even more beautiful
once these changes have been made
I then proceeded to paint everything
both the chest and the gate in slate color
because I wanted to reproduce
in the last 10 to 15 years
it was first painted in ash gray
and at the beginning it was in the classic red wagon
on the bottom of the cart then I made two holes
I made them before painting
but it would not change much
to allow the wires to pass and then go to the hooks
inside the cart was also included
a burden
a piece of metal
which was used to give weight to the wagon
this piece of metal
as I had already shown in the other video
it was rusty
so I proceeded to clean it
and give it a coat of anti-rust
and some color
You will not see but at least avoid rusting
and to make powders inside
Once you've done this
I proceeded to reassemble the various parts
and then to insert the Decals
I got the Decals from a site
that I am enclosing in the description
I believe they are though
for the wagon of the 90s
the one in ash gray
I took the main ones
and I did not put them all at all
I also then took it
since as I said in the video
the acme I think put
a single sachet of additional items
the pieces of the REC
both male and female
from both sides
I painted them
and I put them
in the wagon
as a touch of class
all the pieces were black
so I left the black wires
and both male and female attacks
I painted them gray
metallised, exactly like the roof
in fact the roof was also painted
for the plasticard it was yellow
to make everything solid
I used the classic Märklin conductive hooks
with a thread welded to them that goes inside
and I used it in the roof
a piece of copper
that I had previously pierced
in order to pass the screw
to switch the current
from the pantograph to the wire
all the wires remained inside under the roof
they are neither visible
nor do they give problems to hooks
in their movement
there are still some inaccuracies
but I did not want to change
as the bumpers
on the side opposite the sentry box
they should be stretched
spaced with respect to the cart
this because there are rules that
provide a minimum distance between wagons
for these electrical connections
this change could be done
on a wagon made with the TTM kit
because the bumpers are a sum of several pieces
in this case the bumper is
integral part of the mold
and so I could not detach it
if not risking to really break
different pieces of the case
To prevent the wires from being visible
from the cash desk
I painted them all in black
to make them look like conduits
the final result will then be visible at the end of the video
as now with the following light conditions
I can not let you see it
In the continuation of the video we will see then
the finished result
it's a test
of the various electrical connections
made with a Corbellini
and with the Carriage Try Hooks
here it is
finally finished
after several weeks of work
we find the 2 hooks
connected via this wire
that has been painted black
and then there is a branch in it
where the 2 wires are joined and connected to the pantograph
all 3 are electrically
acts for operation
are there any problems
and mistakes
the first of all is that the Decals
in question they are actually for the cart
not in slate gray
but for that gray ash
the previous version
I realized it only later
so this is a historical inconsistency
another mistake
is that the Decals
they were made
from private individuals
and not on an industrial level
so you had to cut it yourself
and the result did not come
a great deal
mostly
here it is clearly visible
the sum of the two
one above and one below
besides being of a different type
one has been ruined
and here it is missing
the service number
as here
the acme wagon has undergone
of cuts
here on the carts
there were small grilles
that now there are no more
they broke during the various jobs
they were too delicate
and it did not change anything
do not have them
so I preferred not to put them back
the ACME model
for this type of change
it is not too recommended
unfortunately I realized it
too late
as it is really very delicate
and presents a series of details
that do not do anything else
that make it very difficult
work
they would also miss the Decals
in this lower part
as I realized that the written
they're too big
compared to this model
probably
the carriage F
for which the Decals are made
that is the TTM kit
has tolerances
constructive
more than they make
then the writing is bigger
this that should be in perfect H0 scale
in fact it is very difficult
to modify
I do not recommend it
I do not recommend the work I did on it
the pantograph if one looks
it is not perfectly straight
but be able to puncture exactly
in the center on a curved roof
it is a very difficult operation
for the rest I would say that it came pretty well
the batteries have been glued
in the right way
I would say that now the only thing we miss
to see it
coupled with the Corbellini family
the wagon can be put
quietly in a composition
as a passing carriage
because the hooks are
both electrified
and therefore allow
the passage of current from a carriage
equipped with a skate
or a locomotive
directly to the cars behind
In the use that I have in mind
it will be paired with Corbellini
and a locomotive NOT able to supply power
therefore it will work
as a means
to illuminate the Corbellini
through the airline
we also do
a check
on the pantograph
to understand if it actually works
we will use an ammeter
linking
in "current measurement" mode
between the carriage try hooks
and our VRE tank
we will go to see consumption
of the
Corbellini carriages
you are seeing a
8 - 9 mA
the measurement is in alternating current
because of the signal
digital
which also allows the use
of very small threads
because the amount of current
it is very limited
the project is finally finished
we had been carrying on this summer
I hope you liked it
it did not come perfect
There are some mistakes
I know
however, in a plastic use
we can consider modeling licenses
not related to reality
and can therefore be accepted by closing one eye
