MECHANIZED MAINTENANCE OF TRACK ON THE JNR

The Japanese National Railways are making continuous efforts to mechanize track maintenance work in line with the policy towards general modernization of operation. Emphasis is laid on the wider employment of small-sized equipment which will allow a train to pass or which can easily be taken out of the track when a train is coming. So-called overall track renewal using heavy equipment is carried out where an interval of 3 or 4 hours is available between midnight and 4 o'clock in the morning as in the case of the electric multiple unit train lines in and around Tokyo and Osaka. This method is also used on some trunk lines, such as the Tokaido Line in cases where sufficient work time is available by blocking one side of the double track. Outlined are the principal kinds of maintenance work in which such equipment is used, and the measuring devices.
