The series C 4/5 2601-2619 were steam locomotives of the Swiss Federal Railways (SBB) that were procured for use in front of freight trains . Most of the locomotives were later converted to E 4/4 shunting locomotives .
history
After the nationalization of the private railways around the turn of the century, there were many obsolete locomotives in the SBB's inventory, which is why more powerful machines were quickly required. A first series C 4/5 with the numbers 2701 to 2732 was procured from 1904 to 1906 and designed as a four-cylinder compound machine.
The concept of 32 locomotives seemed to prove its worth, which is why a further 19 locomotives were procured between 1907 and 1912, but these were designed as superheated steam twin engines with smoke pipe superheaters of the Schmidt type . The locomotives with the numbers 2611 and 2612 were specially designed with direct current cylinders of the Stumpf design . It did not prove itself, so that these locomotives were retired in 1926 and 1931.
The last four machines in the series were designed for use on the Gotthard Railway . The boiler was larger and had a pressure of 13 instead of 12 bar. The adhesion weight increased to 60 t. The 2618 also received a Knorr - feedwater .
Because of the electrification in the 1930s, the mainline locomotives were no longer needed and were converted to type E 4/4 shunting locomotives from 1930 to 1933, whereby the leading axle was dismantled and the tender was dispensed with. All machines were rebuilt except for those with stump DC cylinders.
commitment
The first 15 locomotives came to the Brugg depot in the former SBB District III and were mainly used on the Bözberg line. The remaining locomotives were used on the Gotthard Railway .
