Reflecting British Railways’ fondness for naming its engineering vehicles after marine wildlife, hundreds of ‘Seacow’ and ‘Sealion’ ballast hoppers entered service in the 1970s. Many remained in front-line use until 2016, when the final examples were withdrawn.
The key difference between the two types is that ‘Seacows’ are air-braked only while ‘Sealions’ are both air- and vacuum-fitted. With a 40-ton ballast capacity, the hoppers could be seen across the country both singly and in rakes (often paired with a ‘Shark’), making them ideal candidates for O Gauge layouts large and small.
