The Swiss Central Railway ( SCB ) procured a total of 10 class E 3/3 shunting steam locomotives between 1873 and 1874 . Initially, they were referred to as the F 3 series by the railway administration and delivered by the Swiss Locomotive and Machine Factory (SLM) in Winterthur. The purchase price is given as 42,000 Swiss francs.

Technical

The shunting locomotives were the first of the SLM's 3/3 wheel arrangement and can therefore be described as the ancestor of the E 3/3 , which were supplied by the SLM.

The locomotive, which was built on an inner frame, had an axle base of 2600 mm. The boiler was relatively small and its center was 1,820 mm above the top of the rail. The kettle carried a steam dome in which the slide regulator operated with normal levers was located. It was operated using levers on the rear wall of the boiler in the driver's cab. The driver's cab was initially open at the back and sides, but later a rear wall was used. The fire box could be placed over the axles. It was of the Belpair design and had an excessively flat lid. The Ramsbottom safety valve was also on top of it. The water tank was built into the inner frame in three parts and was partly under the driver's cab. On both sides of the driver's cab, next to the fire box and boiler, the charcoal boxes were attached. The engine acted on the rearmost axle, which was connected as the drive axle to the other two axles by means of coupling rods. The control was one of the Allanbauart with crank eccentrics, which operated the slide rods via reversing double levers. The piston rods were carried forward and protected by a sleeve. All suspension springs were above the frame. The compensation levers were arranged lengthways between the 2nd and 3rd axles and transversely between the rear support of the front axle. A four-block spindle handbrake was installed, which acted on one side on the middle and rear axle. There was also a sand dome on the boiler, the downpipes of which could sand the central axis on both sides. After 1893 steam heating was installed in the locomotives.

Machines of the Dreispitz area

The following changes were made to the locomotives (8581 + 8586) sold to the Dreispitz warehouses around 1924/26: The steam dome was increased. The safety valve was located on it. The chimney has also been shortened. A lubrication pump and central lubrication devices were also installed. The brake spindle was moved to the right side in order to be able to operate the machines with one man.

Operational

At the SBB, the locomotives were assigned to District II and thus also to their old Olten workshop.
