Units industry road trains
G-volution Ltd have been involved in dual-fuel technology for the truck sector in the UK for the past 8 years. Now it is applying that expertise to the rail sector. The project involves modifying one vehicle on a Grand Central Class Diesel Multiple Unit to be powered by dual fuel. This can help reduce fuel costs, particulate matter and CO2 emissions. One of the aims of the trial is to demonstrate the path to market and effectiveness of a dual fuel solution, helping to facilitate an industry uptake of the technology. It is expected that the actual vehicle modifications will be straightforward, to be confirmed as one of the anticipated outcomes of the trial.VIDEO ON THE TOPIC: The Railroad Journey and the Industrial Revolution: Crash Course World History 214

Advances in rail industry technology reduce road failures for freight trains
In simple terms, the more cattle a single prime mover can pull within maximum allowable length limits and in keeping with animal welfare and road safety standards, the more efficient its operation can be.
The most common long-distance configurations used in the north are six-deck triple road-trains and the B-Double and dog-trailer combination, but now four-trailer configurations which can add a full extra deck within the Mr Leeds and his son Justin were driving a triple road-train back from Queensland in the s when they began tossing around the idea of adding a fourth trailer to shift more cattle.
We figured that if we could use seven-deck units with each prime mover, we could load each boat far more quickly. With the help of their good friend the late Dennis Buntine, the oldest son of NT livestock transport pioneer Noel Buntine and the owner of Territory Transport Sales and Victoria River Transport, the Leeds began designing a combination capable of incorporating a full seven decks within the While the initial design would have squeezed within the So they went back to the drawing board to trim a further 1.
When the day of judgement came, and they presented their first purpose-built, four-trailer, seven-deck unit to the WA Department of Main Roads for measurement, it came in under the The Leeds' seven-deck unit effectively takes the form of two dog trailers and a B-Double.
Three of the trailers in the configuration are Mr Leeds said the configuration effectively means his drivers can cart an extra deck of cattle with every prime mover. Or, put another way, they can carry the same number of cattle with six prime movers that it would normally take seven triple-road trains to move.
The seven-deck units have a gross weight when fully loaded of up to t. For the 14 years the units have been in use by Leeds Transport they have been comfortably pulled by prime movers rated at t.
Mr Leeds said the additional deck did not add significantly to fuel consumption. His advice is that the units are best operated in a total purpose-built configuration, rather than being put together by mixing and matching existing trailers and dollies. From a physical handling perspective, Mr Leeds said the configuration was very stable, but it was important in his view that it be assembled with the two dog trailers hitched at the front and the B-Double at the rear.
In everything that we have done, the B-Double and dog combination is a beautiful combination to tow with the A-Trailer in the middle. The Queensland Government stopped short of granting a special permit to Leeds Transport to tow a seven-deck unit built recently by Haulmark Trailers in Brisbane from Roma west.
Instead the configuration had to be towed by separate prime movers to Camooweal before it could be assembled and towed under a special permit across the NT and back into WA. While Mr Leeds has purpose-built his own four-trailer unit to improve efficiency in northern areas, other transporters have also assembled four trailer combinations using conventional stock crates to increase payload capacity across the north.
The constant challenge as always comes down to finding a combination that can fit within the maximum length limitation, which at times can also mean the difference between using a cab-over or bonneted prime mover.
However some of those efficiencies can still be eroded when transporting cattle from north to south due to WA road rules that prevent quad and triple trailer combinations moving within km of Perth. Longer-trailer combinations moving south from that point must be broken down into double and single trailers. Depending on the dimensions of the trailers involved, that can require two and even three prime movers to tow the same trailers to meatworks near the WA capital. It is also why WA livestock transporters have been long campaigning for the relatively small bottlenecks that prevent longer-trailer configurations from having more direct, safe and efficient access into southern destinations to be addressed.

Indian Railways launches first solar-powered diesel electrical multiple unit train
Railroads are operating on ancient technology platforms that were created long before today's cyberthreats, says Amir Levintal, CEO of rail-focused cybersecurity start-up Cylus. The problem affects only a small niche of industry, but it nonetheless worries many experts and lawmakers. At a February House Homeland Security Committee hearing on transportation cyberthreats, Rail Security Alliance Vice President Erik Olson listed the problems facing transportation, saying technologists "apply technology across every aspect of the nationwide freight rail network, effectively increasing the vulnerability of industrial control systems, train operations and perhaps even the industry's metadata warehousing centers to cyberthreats. In the last several years, North Korea has reportedly tried to hack South Korea's rail transit system, and criminals have used ransomware to shutdown metro operations in Germany and San Francisco. Rail systems are vulnerable in two primary ways, which Cylus serves: first in how tracks are operated with signals, stop signs and pedestrian crossings, and then, within the ticketings systems, and onboard trains, where heat, air conditioning and safety functions are managed.
In the road transport or trucking industry a B-train consists of two trailers linked together by a fifth wheel , and are up to The fifth wheel coupling is located at the rear of the lead, or first, trailer and is mounted on a "tail" section commonly located immediately above the lead trailer axles. The twin-trailer assembly is hooked up to a tractor unit via the tractor unit's fifth wheel in the customary manner. An advantage of the B-train configuration is its inherent stability when compared to most other twin trailer combinations, the turntable mounted on the forward trailer results in the B-train not requiring a converter dolly as with all other road train configurations.
Class I railroads continue the longer-train trend
The implementation of hub-and-spoke networks in intermodal transport is suggested as one of the potential solutions for helping to increase the intermodal market share. Traditionally, trains are shunted at hubs; this is a time-consuming process. Since the early s a new type of intermodal terminal, specifically designed for fast transshipment at nodes in hub-and-spoke networks, has been introduced in Europe. These hub terminals could replace this time-consuming shunting. Studies on the new hub terminals suggest that they may perform more efficiently than shunting yards. However, a systematic comparison to reveal the operational and costs differences between shunting and these new hub-terminals for a broad range of situations still lacks. The main objective of the study was to develop a model to identify favourable operational conditions for new hub terminals to be implemented and to quantify their operational performances in relation to alternative hub exchange facilities. Simulation models were developed to study rail-rail exchange operations at new hub-terminals, hump and flat shuntings yard and road-rail terminals.

By converting the electrical multiple units EMUs to what Alstom describes as a hydrogen multiple unit HMU , the Paris based firm will combine the efficiency and practicality of the existing rolling stock with the versatility and environmental benefits of hydrogen fuel cells. T he railways need to decarbonise and the Government has rightly set out a goal to eliminate diesel rolling stock by The Breeze offers British rail users the opportunity to share in the pleasure that is a journey on a hydrogen train. The trains will be converted by Alstom and then owned by Eversholt, which will then lease them to rail operators. They are unlikely to be of much use on networks with widespread electrification such as those found in the South East of England but in areas without third rails or overhead lines, the HMUs will deliver much-needed zero-emission mobility.
Cary, NC - The rail industry estimates that advances in detection technology are preventing more than road failures monthly on the North American system, based on preliminary statistics for the year Increased efforts to identify the causes and further understand issues that affect freight rail performance and safety continue. Summey said data flowing from a number of wayside detectors and train events help single out the cause of road failures. He says those detection networks are getting faster and smarter.

A road train or land train is a trucking vehicle of a type used in rural and remote areas of Australia and in the United States and Europe , to move road freight more efficiently. Early road trains consisted of traction engines pulling multiple wagons. The first identified road trains operated into South Australia's Flinders Ranges from the Port Augusta area in the midth century. During the Crimean War , a traction engine was used to pull multiple open trucks.

Pulling well more than cars, the trains are much longer than — and in some cases more than double the size of — a typical 5, to 6,foot train. Canadian Pacific , CN and Union Pacific Railroad have incorporated long trains into their operating strategies and continue to aggressively push the length envelope. When it comes to the reasons for lengthening trains, all the Class Is are in unison: to boost productivity, gain more efficiencies and cut costs.
