The United Swiss Railways purchased in 1875 for the local and shunting 17 Tender steam locomotives of the type Ec 2/2 , the last two machines already on the SBB were delivered. None of the locomotives that were designated E2 by the VSB have survived.
procurement
The first three machines were built in 1875 in the VSB workshop in Rorschach based on the NOB model. The first reorder went to the Sächsische Maschinenfabrik in Chemnitz with four machines in 1876 . The second and third reorders with two machines in 1881 and three copies in 1885 were placed with the Esslingen machine factory . The fourth reorder in 1894 with three machines and the two machines in 1902, which went directly to the SBB, were supplied by the Swiss Locomotive Factory Winterthur (SLM). The purchase price was between 33,000 and 37,500 Swiss francs.
Technical
The locomotives with a wheelbase of 3000 mm reached a top speed of 60 km / h despite the small wheel diameter of 1210 mm. They had an inner frame with a water box. The boiler was 1800 mm above the top of the rail and had between 130 and 136 boiler tubes with a length of 3542 mm. The fire box stood over the rear axle. The suspension consisted of four independent suspension springs above the frame. A Walschaert control was installed for the first time in a VSB machine, but this was modified according to the Klose system. In the case of a straight backdrop, as with the all control, the pivot point was raised or lowered opposite to the adjustment of the thrust reverser rod. The controls were operated by lever actuation. The piston rods were not carried forward. The sandpit was initially on the running sheet, but later a sand dome was attached to the boiler. In addition to steam heating, the machine had a Klose speedometer, which was located next to the long boiler. The four-block brake on the drive axle was operated with an external brake (hand brake). From 1891 an automatic Westinghouse brake was installed, which worked on the same brake blocks. The brake cylinder was mounted on the left running sheet, the air cylinder installed across the cab under the driver's cab. 3.1 m³ of water and 1 ton of coal could be carried as operational supplies.
The replacement boilers all come from the Swiss Locomotive Factory in Winterthur.

1 These names were carried over from the Eb 2/5 sold in 1863 .
2 numbers probably changed due to boiler replacement.

Operational
The machines were allotted for the maintenance of the Rorschach workshop and thus to SBB district IV.
Conversion into heating car Xd 99001–99005
In 1919 the 6075 locomotive was converted into a heating car. The 6071, 6076, 6078 and 6082 followed in 1920. The cylinders, together with the inlet and outlet pipes, the engines and the controls were removed. The wheels were unbalanced by drilling out the tapping hub and counterweights. The locomotives were fitted with a car body and the heating station was completely closed. It was thus possible to cross the heating car while driving in order to get from the locomotive to the passenger car. The Westinghouse brake was expanded to 8 blocks. The frame had to be extended to a wheelbase of 3400 mm to enable a top speed of 75 km / h. In 1927/28 it was extended to 4100 mm in order to increase the top speed to 90 km / h. The water supply was increased by an additional water tank on the right. The empty weight of the heating truck was 22.5 t, the operating weight 26.2 t.
