| West Japan Railway Company Orders Rail Re-Profiling Vehicle |
| |
The Sumikin Bussan Corp. (hereafter "Sumikin Bussan") has received an order from the West Japan Railway Company (Head office: Osaka; President: Masao Yamazaki; hereafter "JR West") for a mobile rail re-profiling train to be purchased from Linsinger Maschinebau G.m.b.H of Austria, one part of JR West's investment in safety.
The type of rail re-profiling currently conducted in Japan is the "grinder method," which uses a rotating whetstone. JR West's introduction of Linsinger's "milling method" using a carbide-coated blade will be the first time this method is used in Japan.
Re-profiling of rail surfaces is regularly conducted by JR West and other railroad operators as part of their safety and environmental measures. The rail surface becomes worn from trains passing over them. Rail re-profiling removes the worn-out rail surface and extends the life of the rail while at the same time decreasing noise created by trains running over the rails.
This order enables Sumikin Bussan the opportunity to expand its domestic sales of Linsinger's mobile rail milling trains to other domestic railroad operators. |

♦ Advantages of the milling method for rail re-profiling
| |
(1) |
Rail damage suppression |
| |
|
Until now, rail re-profiling has been conducted by the grinder method using a whetstone to scrape the rail surface, however, the milling method uses a blade to push down and shave off the damaged rail surface. The grinder method re-profiles to a depth of 0.01mm to 0.02mm, whereas the milling method can re-profile to a depth of 0.3mm to 1 mm. Deeper rail re-profiling results in the suppression of rail damage and the prevention of fracturing. |

(2) |
Reduced maintenance times |
| |
|
The grinder method of rail re-profiling requires the grinding process to be repeated dozens of times on the same section of rail just to scrape off the top 0.3 mm. Maintenance using the milling method requires a single, one-way pass over the rails, enabling a reduction in the time required to conduct rail re-profiling. |
