Minho e Douro No. 40 “Penafiel” and No. 41
Portugal | 1902 | 2 produced
Locomotive Magazine, January 1903

While the 0-6-2 wheel arrangement was often used in tank locomotives, it was very rarely found in tender locomotives. Two of these exceptions were number 40 “Penafiel” and 41 of the Minho e Douro. They were built by Hanomag, although they basically had a British look. This included the low running boards with the wheel housings for the drivers. However, contrary to British practice at the time, outside cylinders were used, although the broad gauge in particular would have been perfectly suited to accommodating not only the valve gear, but also the cylinders within the frame.

Although the 0-6-2 wheel arrangement is usually assumed to have a radial trailing axle, the trailing axle on this machine was apparently fixed to the frame. A noticeable feature was the dust cover around the first coupled axle, which was intended to protect the valve and drive gear. Following German and American practice, the sand dome was situated on top of the boiler to protect the sand from water. A speed recorder was also installed, which was still a rarity for later steam locomotives.
