Trio with five rails

Der Mittagszug, heute bespannt mit der V 51 der PRESS rollt langsam am gut besuchten Biergarten vorbei.

How are new rails on your LGB layout transported to the trackmen? Reinhold Braun has transformed a set of three stake cars into a rail transportation system for narrow-gauge railways.

Small  prototype large replica: The idea for the rail transport car came from a Marklin HO model (item 45095).

The idea for the construction of a three-part rail transport vehicle did not come from a specific proto-

type of a narrow-gauge railway, as is the case for most building tips in LGB Depe­sche, but from an actual Marklin model. Specifically from the HO car 45095, a set of three flat cars connected to each other by spacer bars. The three connected cars transport long track profiles. Marklin has loaded the cars with eight reproduction rails. They are made of flexible plastic and are therefore mobile enough to also handle cornering without any problems. What Marklin offers in HO format can also be created with manageable effort as a three-part rail transport car in G-gauge. Measuring almost 3.3 feet in length, it is quite a sight.

Base material

The 9.8″ long LGB stake cars of the Ger­man State Railroad (DR) are suitable as the base material for the rail transport car. Three cars are required. The pivot plates and pivoting arms are taken from the LGB dual flat car (LGB item 4050/40500). The cars are equipped with forest railroad couplers and interconnected by means of two drawbars. The drawbars are manu­factured by Reinhold. Alternatively, plas­tic bars from LGB logging trucks can also be used. Visual details such as a plate with screw heads or dummy rivets can be added as desired. The operating characteris­tics of the long car can be improved   through ball bear­ing mounted wheel sets (LGB item 67403).

Building phase 1:
Attaching turntable plates and pivoting arms

For assembling the carrier plates, turn­table plates, and pivoting arms as well as for further processing of the chassis, the cars and the pivot plates are dismantled into their individual parts and the dummy brake hoses are removed. After the car­rier plates with the pivot plates have been removed from the original model, they are attached to the stake car. For visual reasons, installation is different from the original pivot plate car. The carrier plates are not fitted longitudinally in the direc­tion of travel, but transversely. This en­sures the plate is easier to see on the car when loaded. To fix the pivot plate firmly to the car, the carrier plate is not only glued to the pivot plate, but the anchoring pins of the plate are also used. This means the pivot plate is seated more securely on the car. Since the carrier plate with its pins is asymmetrical, installation is somewhat tricky. The use of a light railroad truck superstructure from the dual flat car (LGB item 4050 or 40500) as a drilling template facilitates work. But be careful: The injection molded lug on the truck leads to the assumption that the center point is here. That is not true, it is offset by 0.07″ in the longitudinal axis. A 0.03″ hole is drilled through the center of the carrier plate into the truck superstructure so that the light railroad truck drilling template can be inserted centrally on the stake car superstructure. Subsequently, a hole of the same size is drilled into the center of the stake car superstructure. A small pin is inserted into the stake car hole and then the truck car template is positioned so that the pin makes contact with the drilled hole in the template. The drilling template is positioned at a right angle on the stake car.

Präzise Bohrung: Um die Verankerungs­zapfen präzise auf den Aufbau des Run­genwagens setzen zu können, wird der Aufbau der Feldbahnloren als Schablone genutzt.

Precise drilling: In order to be able to ilace the anchoring pins precisely on the uperstructure of the stake cars, the su­ierstructure of the light railroad trucks is sed as a template.

The retaining holes for the pins can now be marked on the carrier plate. Using a 0.12″ bit, the holes for the pins of the carrier plate are then drilled into the stake car. The pins of the carrier plate are inserted into the holes, addition­ally the carrier plate is glued into position on the stake car superstructure using a plastic adhesive (for example: Technicoll TC 8008).

Installation and conversions in the chas­sis area

The cargo to be transported, in our case five plastic track profiles, is not particular­ly heavy but it nevertheless demonstrates considerable lateral leverage. For reasons of operational safety, the three cars there­fore need to be weighed down with ballast weights. The additional weights are in­stalled between the axle support frames. After various trial runs, a minimum bal­last weight of 1.7 lbs per car was deter­mined. To provide this amount of weight in a fairly compact form, Braun uses metal – as heavy as possible. A block measuring 2.80″ x 1.73″ x 0.87″ is cast from the lead. It then fits perfectly into the center sec­tion of the chassis. The block of ballast is attached to the chassis and the stake superstructure. To achieve an even adhe-

sive surface, the excess injection molded lugs underneath the car superstructure must first be ground flat. Reinhold Braun uses plastic adhesive to fix the blocks into place. With their additional weight of 1.7 lbs each, the three transport units were able to negotiate the test route featuring curved LGB tracks (radius 3) and also the counter curves with 16000-series switch­es without any problems. However, trial operation with lighter additional weights (0.99 lbs) underneath the cars resulted in problems on the test route. To improve the running characteristics, all three cars are equipped with ball bearing mounted wheel sets.
