Steam locomotive class 2-3-1 Gr. 691
Steam locomotive with tender Gr. 691-023, for passenger service on the FS.
For hauling high-speed trains, the Office of Studies of the FS prepared a
project in 1928, for the transformation if the existing Gr. 690 locomotives
build in 1911 and 1914 in a total of 33 units by OM, Ansaldo , and Breda works.
Thus the new Gr. 691 class, still maintaining the same wheel alignment of 4-6-2
(2-3-1).
The new locomotives, while retaining the same engines and the same wheel drive
of 690, the C steam generator (boiler) already applied to locomotives other
Gr746 locomotives and it’s rear bogie " bissel” after lengthening of chassis was
done. All these changes contributed in the achieving of significant benefits in
terms of speed (characteristic of Gr. 6K with great hourly steam output with the
Gr 746 generator. The locomotives Gr 691 played from their entry in to service
in 1928 onwards, until 1962 the important task in hauling convoys of passengers
on the most important rail routes in Italy.
The model represents that
of the prototype Gr. 691-023 in its original condition with 22m² tender of 1931.
The attention paid to detail in noted, right down to the braking system and the
bogies fitted with suspension. Walschaert gearing and operating front head
lanterns.
Length of the model cm. 28
Produced by Rivarossi from 1950 until 1994
The first models were produced
in all metal cast by Cos.Mo. for Rivarossi.
Production in plastic begins only in 1962
