In 1876 the Wohlen-Bremgarten-Bahn ( WB ) acquired two Ed 3/3 tank locomotives from the workshops of the Schweizerische Centralbahn (SCB) in Olten . The purchase price is given as 33,000 Swiss francs. The locomotives came to their rolling stock with the conclusion of the 1883 operating contract with the SCB. There they were initially listed as the E 3 series.
Technical
The SCB workshop in Olten built the two locomotives as a light version of the SCB Ed 3/3 . The same type of boiler was used , but the boiler was a little deeper, at a height of 1650 mm. It did not have a steam dome , but there was a sand dome and a Crampton case on top of it. The slide regulators operated by levers were located in this housing. The outer inlet pipes also led from the housing to the cylinders. The three spring balance safety valves were located on the regulator housing and fitting dome. The wheelbase was lengthened compared to the SCB locomotives, so that the fire box found space between the second and third axles and the rear overhang could be avoided.
The locomotives had an inner frame. The suspension springs of the first and second axles were above the frame, the third axle was provided with transverse suspension. The oval water boxes were attached to the side of the boiler and the coal box was behind the driver's cab, which was open to the rear. The control was an Allan control with an eccentric, and a double lever arrangement was switched on through the long drive rods. This reversed the control movement and moved inwards to control the slides on the cylinder axes. The reversal was carried out by means of a lever via a two-part control rod and a control shaft running through under the driver's cab. The four-block handbrake, equipped with an inclined spindle, acted on the drive axle.

Operational
In recent years, the locomotives have performed shunting tasks in Basel, where they have been given the nickname "Char à banc" by the staff because of their appearance.
