B.C. in Asia, although the oldest wheel that has been discovered in Mesopotamia and dates back to 3500 B.C. (ThinkQuest,2010). Along with the wheel and domestication of animals, great inventions came along such as the chariot and more modernly the horse drawn carriage. Although these types of transportation are vital in third, fourth and fifth world countries, it is rarely used in developed countries.
Human kind has not been satisfied with animal power. The invention of steam and combustion engine during the industrial revolution has allowed for greater transport and logistical advancements. The steam engine was widely used to in locomotive trains in the eighteen and nineteen hundreds. With the development of further railroads heading west trains became longer and faster. There are disasters that took place one of the most famous explosions of a steam engine occurred on July 3rd 1927, the engine was Maine Central # 505.
'July 3, 1927: Maine Central #505 was in Bartlett having come in on the 'Local' Portland, ME to Bartlett, NH job the night before. The Roundhouse was short on power so the 505 was to be a 'helper' locomotive. It was rare for her to be used as a helper as this was the case for all the Class W's. These were used almost exclusively east of Bartlett, where they really shine.
505 were due to go back to Portland on the afternoon local later that day. She was pressed into service to help with a very 'heavy' extra. She would be put in mid train, and cut off at Crawford's. Bob Morse and Oscar Clemons planned an afternoon fishing trip for when they returned. There would be 2 locomotives on the head pin.
As the Engineer, Bob Morse worked the engine, to help make up the train; the throttle felt 'Soggy'. He reported it to the mechanics at the Bartlett Roundhouse, they checked the loco over, but could not find the problem. Bob and his fireman, Oscar Clemons, went back to work. Again, Bob reported the sluggish response of the 505; the shop crews brought her in to the Roundhouse and did everything but dump the fire and pull the boiler jacket off, which Bartlett was not equipped for anyway.
So at about 8:00 the 505 took her place, on a WESTBOUND extra freight, about mid train. The train departed at about 8:30 a.m.
Bob Morse was a popular man, but pushed his locos to their operational limits, he got every bit of operational power out of the engine he was running, and he was very good.
One trick almost all engineers had in those days been to run the loco water low. This gave you the maximum amount of steam pressure and the maximum performance from the loco, but the engineer had to have a fireman that could handle the task, it was a dangerous dance, but Oscar Clemons had worked with Bob Morse for years and knew exactly what he was doing.
At about 10:00 the train passed Willey House Station, Mile post 81 about 1/4 miles up the track it becomes straight and levels off. The 505 was traveling at 40 MPH under past maximum pressure, when the loco reached this point Oscar opened the petcock for water and the engine exploded.
The boiler failed just in front of the drive wheel 2nd from the firebox (3rd driver from the front). The explosion blew Engineer Morse out of the cab and 500 feet back. The Locomotive lifted clean out of the train, fracturing the connecting bar between the engine and tender, flew up in the air
