Mr. Baldwin’s second locomotive, Old Ironsides, wasn’t one of his own design, though. He was engaged to assemble a locomotive imported from England for a Philadelphia railroad company. Considering that the common tools needed to complete such a new project hadn’t yet been invented or manufactured, the team created their own tools and processes, and slogged through the build with great difficulty. Not to mention that the “kit” from which Mr. Baldwin was to assemble Old Ironsides was not complete: not only were the assembly instructions absent, but major components such as cylinders were not there either. Despite these challenges, Mr. Baldwin and his team designed what he needed and built the locomotive. Road trials began on November 23, 1832, and, with some tweaking of the design, Old Ironsides entered service just three days later, on the six-mile road. Able to reach speeds over 30 miles per hour and pulling around 30 tons, Old Ironsides – with Mr. Baldwin’s design improvements – proved herself to be far better and much more capable than any locomotive then existing either in the US or in England. Such began Mattias Baldwin’s newest career: locomotive builder.
