The country's first ballastless track system PATIL RHEDA is an in-house design and development based on RHEDA system designed in Germany. Our R&D team has customised this for the requirements of the Indian market. It was used in Jammu & Kashmir and for Delhi airport. Ballastless track system can be integrated optimally into traffic flow and the urban landscape whether for tram systems, underground railways or surface commuter train lines. Patil Group of Industries has introduced a complete Ballastless track solution for urban metro rail on viaducts and underground tunnels. PATIL RHEDA Solutions are being used in many places and guaranteed under single point responsibility wherein the complete track, fastening and turnouts are integrated and delivered on a single source making it cost competitive and hassle free for customers and clients. The advantages of using PATIL RHEDA Ballastless track systems include long life cycles, high speeds ride comfort and great load-carrying capability. Practically maintenance free, ballastless track systems ensure 100% availability over many years. In many cases, a maintenance-free track system is indeed the more cost-effective solution over the long run. With Indian Railways still undertaking trial runs with these sleepers, implementation of PATIL RHEDA sleepers has not been widespread. The advantage of these sleepers is its use where ballast cannot be used and especially in tunnels, elevated tracks and station aprons. The use of PATIL RHEDA sleepers is ideal for laying washable aprons at railway stations thereby improving the cleanliness of the station yards. The station aprons where the PATIL RHEDA sleepers have been implemented include Bhubaneshwar and Kacheguda. However, as the requirements of these sleepers is not in very high quantities, bulk production is not very economical or a viable option. Sensing a potential in small quantity manufacturing, Patil Group worked to set up mini mobile production plants - these can reach the station where the apron is required. Once there, the required design can be programmed, manufactured and once the same is laid out, the production van can move to the next location eliminating the need for setting up bulk manufacturing plants and transportation of these sleepers to their destination. PATIL RHEDA Ballastless track was selected for the Jammu-Kashmir railway line. The company has also introduced complete ballastless track solutions for urban metro rail on viaducts, underground tunnels as well.

The Plinth Type Ballastless Track is a well proven design used in more than 10 metro train projects across the world and in different gauges. This design has been developed by Patil Group in co-ordination with leading international design consultants. The continuous plinth track system is a continuously supported rail with discrete shoulders retained by rail clips. The Plinth Solutions can be implemented in the following situations: Elevated track Depots Tunnels & viaducts Plinth system of Urban Metro is meant for speeds up to 80 kmph. Presently, the company is executing the construction and laying of Plinth Type Ballastless Track for the Mumbai Metro in partnership with national and international agencies of repute. Our varied references in this product make us hopeful to aspire for further forthcoming urban metro projects in various cities.

Modern Turnouts A modern turnout is a track structure composed of a switch, a frog and closure rails permitting a train to leave given track for branching or parallel track. The turnout systems can be applied for different traffic applications like: Heavy Haul High Speed Mass Rapid Transit Systems in urban areas All required gauges All track systems as slab track and ballasted track All required rail fastenings The benefit of the turnout systems is based on minimized life cycle costs on account of lower maintenance, higher reliability and shelf life. Most importantly, turnout systems can be tailor-made for specific requirements. Switches The diverging path geometry of the switches is optimised according to the principles of vehicle dynamics. These cuts induce forces and thereby improve travelling comfort and service life.

Automation in the sleeper industry aims at improving productivity, achieving zero defects and meeting just-in-time supply requirements of the customers. As in the past, Patil Group has emerged as a pioneer in the field of automation also. It is the only group in the country to set up new automated manufacturing facilities to cater to the exacting standards of Indian Railways and other vendors. The “Long Line Technology” as the manufacturing process is called, is used to manufacture Pre-Stressed Concrete Sleepers in an automated environment. Some of the biggest advantages that this technology brings over the conventional technology are reduced dependency on manpower and substantial improvement in quality. Also, the casting time comes down by nearly 25% thereby increasing productivity. This technology helps in manufacturing large quantities of sleepers in least possible time. The regular operations of the sleeper plant such as de-moulding of sleepers, cutting of pre-stressed wire, HTS wire drawing are automated using machines. This technology permits relaxation and cutting of the prestressed strands and shakeout of the sleepers with no movement of the shuttering, thus eliminating all problems of maintenance or clearance adjustment connected with the moving parts. The long line system can be applied to any type of fastening: Pandrol, Vossloh, Stedef, D.E. Clips, Denik, KB, etc. The moulds have been designed and created in such a way as to allow changing of the necessary type of fastening simply by replacing the plates with the required cast and housing, the plates being screwed onto the structure of the mould. The adherent wire system provides considerable savings in sleeper production based on the use of normal market products (pre-stress strands or rods) that do not need special processing or accessories - they are simply drawn between the pre-stressing heads, fixed with ordinary prestressing clamps and then pre-stressed.

Patil Group of Industries has proved its presence in the field of Flash Butt Welding for Railway through its Flash Butt Welding plant at Moulali, Secunderabad, India. But, in order to explore the opportunities in various upcoming Metro Projects and DFC, Management has decided to expand this business. We are in the advance stage of procurement of Flash Butt Welding Plant from USA. Introduction Unlike arc welding that is 'line welding' in which the welding point moves along a prescribed line, flash butt welding is 'plane welding' in which the opposed planes are welded at a stroke. Therefore, this welding method is extremely efficient. As far as application of flash butt welding is concerned, on-site welding of line pipes, welding of rails and welding of marine structures etc. can be cited. Flash-Butt Welding of Rails Basics Flash-butt welding is an electrical resistance welding procedure. Electrical current is conducted through the rail butts and is heating them up to the almost liquid phase. Under high pressure, the rail butts are joint-welded. Flash welding is a development of resistance butt welding and is particularly suitable for butt welding complex or larger sections. It is used for a wide range of component shaped and sizes from bicycle wheel rims to rails. More efficient energy input, and a more localized and evenly heated zone can be achieved, compared with resistance butt welding. WELDING SEQUENCE Following sequence is followed during a welding cycle. Preflash Flash Boost Upset Forge Trimming Upset Metal The individual rails of 13 m. length received from steel rolling plants are initially sent to Flash Butt Welding Plant at Moulali, Secunderabad. The individual rails are then welded into rail panels of 10-rail length by flash butt welding technique, which involves pre-heating of rail ends by passing high ampere low voltage current and then the rail ends are cyclically brought closer and separated, which results in heavy sparking between the rail ends. After the rail ends are brought to a molten state, butting of rail ends is done under pressure. Flash butt joints have very high fatigue strength and are preferred to other types of welds. The rail panels of 10-rail length and 20-rail length formed by flash butt welding are transported from the Flash Butt Welding Plant to the field locations by loading into specially designed railway flat wagons. These panels are unloaded at the site through specially designed end unloading chutes fitted to the rearmost wagon. Important advantages of flash butt welding compared with other joining methods Reduces maintenance costs Saves track time Eliminates corrugation No weld filler material Smaller heat affected zone Smaller annealed zone Consistent hardness Highest fatigue resistance Average life equal to the rail
