How fast were steam locomotives

The railway was also empowered to carry passengers in addition to coal and general merchandise. The line was 25 miles 40 km in length and had passing loops along its single track and four branch lines to collieries. It opened in Four locomotives named Locomotion were constructed and were effectively beam engines on wheels with vertical cylinders. In the painting, crowds are watching the inaugural train cross the Skerne Bridge in Darlington.

The movement of coal to ships rapidly became a lucrative business and the line was soon extended to a new port and town at Middlesbrough. While coal wagons were hauled by steam locomotives from the start, passengers were carried in coaches drawn by horses until carriages hauled by steam locomotives were introduced in The first public steam railway in Scotland was the Monkland and Kirkintilloch Railway.

An Act of Parliament authorizing the railway was passed in and it opened in Further, horse-drawn traffic could use the Stockton and Darlington upon payment of a toll. However, it used cable haulage by stationary steam engines over much of its length, with steam locomotives restricted to the level stretch.

These were arranged as an open contest that would let them see all the locomotive candidates in action, with the choice to follow. Rocket was the first locomotive to use a multi-tubular boiler, which allowed more effective heat transfer from the exhaust gases to the water. It was also the first to use a blastpipe, where used steam from the cylinders discharges into the smokebox beneath the chimney to increase the draft of the fire.

As early as , railed roads were in use in Durham to ease the conveyance of coal. The primitive rails were superseded in when Benjamin Outram constructed a tramway with L-shaped flanged cast-iron plate rails plateways.

In , John Birkenshaw introduced a method of rolling rails in greater lengths using wrought iron, which was used from then onward. The first line to obtain such an act, in , was the Middleton Railway in Leeds. The first for public use and on cast iron rails was the Surrey Iron Railway, incorporated in The first passenger-carrying public railway was the Oystermouth Railway, authorized in Key Terms rack and pinion railway A steep grade railway with a toothed rack rail, usually between the running rails.

All modern train engines are electric -- even though they burn diesel or coal oil. You can hear the engines speed up when the train approaches an up-hill grade. The question is -- why are they built with an engine, a generator and several motors instead of the old style direct gears? Hint: Trains have massive loads, widely varying track slopes and diesel engines have a fixed rate operation for peak efficiency.

The old steam engines were usually run well below 40MPH due to problems with maintaining the tracks-- but could go much faster. I seem to recall a 45 mile run before in which a locomotive pulled a train at better than 65MPH Stanley Steamer cars were known to exceed 75MPH. The first practical train engine was built by Richard Trevithick in England in about -- earlier efforts had not have sufficient power to pull any sizeable loads.

His engine was high pressure about psi. Rail tracks for carts originated in the middle ages for mines and other applications. A fundamental problem was the cost of forging such tracks in those days The idea for steam powered locomotives probably originated with James Watt.

I don't know what a side rod is -- do you mean the piston ram on a steam locomotive? On a steam driven locomotive, the piston is colinear with the center of the drive wheels of the train. There are several net locations for railways -- try TGV on a hot-bot or yahoo search. Contribution from a reader While it wasn't part of what I was looking for, I decided to have a look anyways, owing to my general fascination with steam locomotion.

I am aware that this was never intended as a comprehensive answer, there are some parts of it that I would like to expand upon. One such remark is that yes, trains nowadays do use gears, although not like the selectable gears in the transmission of a car. Also, while most steamers used main and side rods to transfer power mechanically from the pistons to the wheels, there were also several families of steam locomotives that used gears and drive shafts as the main method of power transmission.

The main varieties of these engines were known as Shays which had three steam cylinders arranged vertically on the right side of the offset boiler , Heislers which had two cylinders in a Vee arrangement under the boiler , and Climaxes which had one cylinder on each side of the boiler, and turned cranks attached to a large gear box under the boiler.

These engines all used gears and drive shafts to transmit power from the cylinders to the wheels, although the gears and drive shafts on the Shay ran down the right side of the locomotive while those on the Climaxes and Heislers ran down the center of the engine. Such engines were used in applications where raw pulling power, maneuverability and small size were needed at the expense of speed, such as small logging and industrial railroads.

Cities that had once seemed far apart suddenly felt much closer together, because people and goods could move between them in hours rather than days. In some places, new towns sprang up beside the tracks. The earliest railways used horses or people, not locomotives, to pull loaded wagons along wooden planks or iron rails.

The first locomotives burned coal to boil water into steam. The steam provided the power to turn the wheels. Most early locomotives in the United States had funnel-shaped smokestacks and cowcatchers at the front to push cattle off the tracks.
