The railway's engineer
James McConnell obtained the directors' permission in March 1844 to build a new locomotive for the
Lickey Incline. This followed a series of accidents on the incline. One involved a demonstration locomotive by
William Church, called, unfortunately "
Surprise". Its experimental boiler blew up, killing the enginemen, Thomas Scaife and Joseph Rutherford. Their decorative monuments are in
St. Johns churchyard Bromsgrove (and have been restored in 2014), though the depiction of a locomotive on the tombstone is of one of the Norris Locomotives. Then a further boiler explosion on another loco killed William Creuze. The company had been using American
Norris s, which in fact lasted until 1856. The Americans made much of the fact that they were showing the British how to build engines, but they were expensive to import.
Edward Bury had tried one of his
London and Birmingham Railway engines in 1841 but its performance up the bank was less successful than that of an American engine because of the latter's undisclosed but much higher boiler pressure. Another locomotive that had been tried was
Ysabel a built by
Isaac Dodds. McConnell carried out a number of innovations, culminating in his locomotive built at Bromsgrove specifically for the incline, the "Great Britain", reputed to be the first
saddle tank. It was completed in June 1845. It was a six-coupled loco, weighing 30 tonnes, with outside cylinders and an oval boiler. Initially number 38, it was later renumbered 276, then rebuilt as a
well tank in 1853, renumbered again as 300 and withdrawn in October 1861. McConnell continued to seek higher standards in railway engineering. In 1846 he met with
George Stephenson and
Archibald Slate at Bromsgrove. It was at this meeting that the idea of the
Institution of Mechanical Engineers came about. In March 1847 McConnell transferred to the
London and North Western Railway as superintendent of its southern headquarters at
Wolverton. ==Later history==
