RhB ABe 8/12 3501  "Allegra"  -  Willem Jan Holsboer

About the Maerklin/LGB serial model's potentials

The prototype

is a three-car electric trainset made by Stadler Rail in Altenrhein of which the RhB ordered 15 units. These are in scheduled operations since 2010. The appelation "Allegra" is a rhaetoromanian salutation which translates best to "Rejoice !" or "Be glad !".

Having eight driven axles and power of up to 2800kW the vehicles are designed for the numerous inclined lines of the RhB - up to 7% without a rack wheel !

The trainsets are equipped with a dual-power system (11kV, 16 2/3Hz AC and 1 kV DC) which allows for operations on the Bernina line as well as on the RhB's other lines. This provides for a maximum of flexibility since previously required changes of tractive units aren't necessary any longer.

The Dutchman Willem Jan Holsboer settled down in Davos in 1867 and got involved with the development of the local cure and tourism center as well as with the construction of the railway line between Landquart and Davos. Hence he was significantly involved with founding the Rhaetian Railway.

The model

makes an excellent visual impression since it features concerted proportions, a pristine lettering and numerous details - which bear a lot of potentials for improvements.

The meassures described below help to redesign both the model's appearance and its interior achieving more truth to the original. Given the amount of required work and to provide some lucidity, the documentation is split into related sections:

Paint work

Ventilation grids
Insulators and lines
Hoses and fittings

Electrical & mechanical issues

Illumination of destination boards
Illumination of dashboard and driver cabin (analogue)
