The names on the bridge refer to the company of Fletcher and Jennings - from 1857 until 1884, the company they mainly built four and six-coupled industrial tank locomotives, although other goods such as bridge girders, and blast-furnace shells for the burgeoning local iron industry, were also produced. By 1884 nearly two hundred locomotives had been built and the company acquired limited liability as Lowca Engineering Company Ltd. In 1905, the name changed again to the New Lowca Engineering Company Ltd. but it was short-lived. Orders had fallen and, after a disastrous fire in 1912 all production ceased, the company being finally wound up in 1927.
