Contributions made by Sperry Rail Service. Rail Inspection. One of the major problems that railroads have faced since the earliest days is the prevention of service failures in track. As is the case with all modes of high-speed travel, failures of an essential component can have serious consequences. The North American railroads have been inspecting their most costly infrastructure asset, the rail, since the late 's. With increased traffic at higher speed, and with heavier axle loads in the 's, rail inspection is more important today than it has ever been. Although the focus of the inspection seems like a fairly well-defined piece of steel, the testing variables present are significant and make the inspection process challenging. Rail is manufactured in different weights; there are different rail conditions wear, corrosion etc present; there are a significant number of potential defects possible; and the task has to be performed with some speed to reliably inspect the thousands of miles of track stretching across the land. Sperry Rail Service, one of the country's leading inspector of railroad tracks, has been using specialized test equipment mounted on self-propelled rail cars for over seventy years to protect the safety of passengers and freight. This information provides a brief look at rail inspection. The history of railroading is rooted in the production of the first metal rails near the city of Sheffield, England in The rail improved the transportation of materials in industries such as mining. In the first railroad intended for public use was opened for operation between the London docks and Croyden. This first railway, the Surrey Iron Railway, offered a smoother ride than a wagon, but offered no real advantage in speed since draft animals were used for locomotion. However, the first steam locomotive was soon to arrive on the scene. Ina steam locomotive pulled a train of cars carrying several tons of ore for the iron works at Merthyr Tydfil in South Wales. The rails have evolved from cast iron plates to specially alloyed steels, which are rolled to a standard shape and specially heat-treated to obtain the desired properties. The figures above show the progression of rail development. Present day steel rails are vastly superior to their predecessors in both strength and wear qualities, however defects still develop. The heavy loads and high speed of today's trains can cause rails to fail in service unless regular inspections are performed.

Safety is Union Pacific's No. We are always looking for ways to innovate, refine and advance our safety procedures. Track inspections and rail monitoring technology keep our communities safe — mile by mile. A Maintenance of Way employee works on a ballast and tie restoration project in Columbus, Nebraska. Union Pacific trains traverse 32, miles of mainline track across the western two-thirds of the country, delivering the goods Americans use daily. Inspecting track is an enormous undertaking — one the railroad takes seriously. Union Pacific owns and maintains its track. While a minimum number of inspections are required annually by the Federal Railroad Administration FRAthe company determines frequency based on the following factors:. Union Pacific was required to perform ultrasonic rail tests on roughly 40, miles of track inmeaning some sections of our 32,mile network had to be tested more than once. The company exceeded this requirement, testingmiles. No part of our system is left unchecked. Additionally, joints, where two segments of rail meet, grade crossings, bridges and rail crossings where two railroad tracks cross each other are inspected every 30 days ensuring their integrity. Track Inspectors Derrick Beard and Greg Wilson operate an ultrasonic rail inspection vehicle outside Chicago, Illinois, identifying rail defects with high frequency sound, which indicates the rail part needing maintenance. Most inspections are visual. An inspector walks or drives a hy-rail truck down the rails, stopping regularly to measure the gauge, or distance between the rails, as well as examine track conditions. Union Pacific also uses special high-tech equipment and inspection vehicles to look for internal defects not detectable by the human eye. Union Pacific is making considerable safety improvements, reducing reportable derailments across the network by 40 percent from to The company continues exploring new processes and innovations to further reduce that number, with a goal of achieving an incident-free environment. Our team of roughly track inspectors is dedicated to ensuring the railroad is safe and reliable — every day. Each inspector undergoes rigorous classroom and hands-on training before taking a test to earn their FRA Part certification. Although the certification is granted for life, our inspectors are evaluated monthly and receive continuous training. Just like any major league lineup, Union Pacific inspectors have a playbook detailing which section of track to inspect and how often. The schedule can and does change due to extreme weather events, such as snow, torrential rain, tornadoes, excessive heat and earthquakes, and when a potential concern is reported. There are circumstances in which special inspections are conducted, such as when train crews inform dispatchers of a "rough track" or community members who observe abnormalities, such as sparks from a passing train or an uneven grade crossing. When Union Pacific receives these calls, inspectors are dispatched to inspect the track before the next train passes. Union Pacific is dedicated to making our rails safe, relying on daily inspections and technology to detect and identify potential defects. Union Pacific inspectors spend their day in hy-rail trucks, performing visual inspections; however, technology also plays a critical role. Forgot password or User ID?

The rail speeder, otherwise known as a motor car, putt-putt, jigger, crew car, track-maintenance car, trike, quad, trolley or inspection car was invented as far back as when a vehicle was needed to help the maintenance of way crews and track inspectors to move quickly to and from work sites. It was reported that the U. Daimler Motor Company created a gasoline powered rail inspection car capable of 15 mph. Early speeders were human powered pump types later followed by gasoline powered engines. These cars were used by the railroad to transport workmen and supplies for maintenance. Typically the car has a front windscreen, roof, and rear bulkhead, the sides being open. This speeder was one of many used on the Nfl. Railway by workers responsible for maintenance, repair, and upkeep of the tracks on the railway. The enclosed cabin had seating for four persons while the trailer could be loaded up with tools, ties, and other equipment. Because of this, they must slow down or stop at crossings and make sure no cars are coming before crossing or flag the crossing if traffic is heavy. Although it is slow compared to a train or car, it is called speeder because it is faster than a human-powered vehicle such as a handcar. They also had to get special permission from the dispatcher to use the track. A privately owned Fairmont MT speeder on display at a model railroad show in February In the s, these types of speeders were replaced by pickup trucks using flanges wheels that could be lowered for on-rail called road-rail vehicles or hi-rails for highway-railroad. Various railways and their workshops also manufactured speeders, but today, Fairmont is the only major speeder manufacturer still in business. After buying Tamper Inc. The speeders left from the earlier days are now owned by hobbyists and can cost several thousands of dollars to rebuild and maintain. Former Queensland Rail Australia speeders. People buy and refurbish these and ride them around on abandoned track. Speeders are collected by hobbyists, who refurbish them for excursions organized by the North American Railcar Operators Association in the U. The Speeder — A motorized vehicle formerly used on railroads around the world by track inspectors to transport work crews and equipment. Jun 23, David Goran.
