The E2 class included several features found on other LB&SCR classes including an I2 class boiler to accommodate the Weir pump and hot water injector for use on high-pressure steam. [1] They had slotted frames, six small 4 ft 6 in (1.372 m) driving wheels, and a water tank capacity of 1,090 imp gal (5,000 L; 1,310 US gal).

[4] [5] The steps produce considerable energy dissipation along the chute [6] and reduce the size of the required downstream energy dissipation basin. [ 7 ] [ 8 ] Research is still active on the topic, with newer developments on embankment dam overflow protection systems, [ 8 ] converging spillways [ 9 ] and small-weir design.
Such was the popularity of boating that in 1877 the navigation commission stationed a boat and crew in busy days above the weir in case of accidents. [2] The lock was rebuilt in 1906.
