Received the following via email from one of our regular correspondents.
What a clever and crazy conglomeration
of coordinated carrying capacity (84 years ago, or even now)! A silent
film clip, but it must have created quite a cacophony and echo of clatter as its
flanges clicked and clacked whilst cleaving through curving track crossovers. A
derailment would create a massive crisis and conundrum and require a call for
several big cranes. Transport with this cantankerous caravan had to thus be
continuously conducted calmly, coolly and with considerable care for the
consigned cargo until terms of carriage were concluded.
Film, less than 90 seconds.
