We are all very familiar and comfortable with the train journeys. Being one of the longest and fastest locomotive services, millions of people depend on this commutation service. But have you any thought of the problems incurred and the solutions possible on the railway lines and train servicing? How can we access the railway lines at remote areas and do the proper repairs on time? For that, we can use a specially designed vehicle known as road-rail vehicles.
What is a road-rail vehicle?
We use road-rail vehicles as a dual objective vehicle which operates both on the normal roads and railway tracks. The combination of the high way and railway make them as high-rails. The designers manufacture them with the normal rubber tires for road operation and flanged steel tires for rail operations. As per the normal design they are road vehicles, in which the propulsion takes place through the rubber tires. As per the need, one can lift or lower the rail wheels. These rail wheels are free rolling and no interventions happen in the normal road locomotion. Road rail vehicle can play an important role in the maintenance of the railway tracks and trains.
As we know the profound use of the road-rail vehicles is in maintenance, how that will reach up to the destination is the main question. On the roads, we can drive them as normal vehicles up to the site. For the final journeys, we can convert it into a rail vehicle near the worksites. The complexity of accessing the far away from rail sites are avoided with these road-rail transports. The normal insulated design of these vehicles helps them to stay apart from the activate track signalling circuits. If you want to include them under the train safety system, non-insulate the vehicles and they will come under detectable range.
The RRVs in different areas
As technology advances, the Railroad trucks find uses in different areas of operation. The main areas include the following.
- Overhead electrification
- Flash-butt welding
- Mast foundation
- Mast erection
- Railway line inspection
