Class C5A 4-Cylinder
Compound Passenger Locomotive
Designed by Karel Belčamin
Rebuilt from Class C5 in 1899 by RSR Works, Bevice-Akohniçe, Ruhnia
Toward the end of
delivery period of the original C5 4-6-0s, their boiler capacity was
barely adequate for keeping time with the ever-heavier trains of the belle
époque. Belčamin had already started work on a new boiler
the C5s a year earlier, and was able to fit it to the last ten new
to be delivered. By 1901, a further 20 locomotives had been rebuilt,
class C5A. The larger grate and higher pressure made a big difference
performance and economy. The crews were not so keen, however.
engines were considered difficult to fire, which was blamed for a
shyness of steam, whereas the older C5 class was trusted and revered.
upshot was that Belčamin had to design another boiler, with which over
half the class was rebuilt from 1901 onwards, becoming class C5B.
