摘要： PURPOSE:To prevent splashing of small crushed stones due to wind of a running train by dispersing over crushed stones on the floor of a rail an ethylene/vinyl- acetate copolymer resin emulsion whose nonvolatile matter is in a specified weight range, and thereby integrating large and small crushed stones on the rail floor. CONSTITUTION:The viscosity of an ethylene/vinyl-acetate copolymer resin emulsion having a nonvolatile matter of 50 to 70wt.% is adjusted to increase the efficiency of the coating operation. This emulsion is dispersed over crushed stones of the ballast and then a pressurized air is blown onto the ballast surface so as to bond together, for integration, the large and small crushed stones of the ballast. This prevents the splashing of small crushed stones due to wind generated by a running train, and also prevents powdering of such small crushed stones at the levelling for rail maintenance to muddy the ballast with the lapse of time.

摘要： PROBLEM TO BE SOLVED: To introduce an axle box in a device for changing a wheel interval during unlocking surely, open and close a lock and change a track gage surely and provide at a low cost. SOLUTION: A track gage changing means 10 formed by a long material alienates narrow/wide running rails 11, 12. Side guides 15 are projected along support stands 9, 9. Right and left guide areas (a), vertical guide areas (b), first balance guide areas (c), operation areas (d) and second balance guide areas (e) are formed in order towards the track gage changing area (f) from both ends of a track side device 13. Both ends of the side guide 15 are expanded in the area (a). The height of the running rail is made constant and the support stand 9 is descended as heading for the outside in the area (b). In the areas (c), (e), the side guides 15, 15 are parallel with a track center (o) and in the area (c), respective support stands 9 are vertically parallel with the running rails 11, 12 and in the area (e), the height of the support stand 9 is made constant and the rail alienate part is provided. In the area (d), the height difference between respective support stands 9 and running rails 11, 12 is enlarged as approaching to the area (f).

摘要： PURPOSE:To make a train travel either on an upper guide way or on a lower guide way of a double-deck structure comprising a turnout track and a main track by moving both of girders for the turnout track and girders for the main track, or either of the former or the letter in the upward or in the downward direction. CONSTITUTION:Girders 3, 16 for a turnout track and a girder 4 for a main track are laid in a double-deck arrangement. Crossbeams 14, 18, 20 are arranged to the underside of the longitudinal ends of the girders 3, 16 so that the crossbeams traverse the girders. Driving devices are provided to make the crossbeams 14, 18, 20 move vertically and, at the same time, guide members are provided so that the vertical movement of the crossbeams can be performed correctly. Locking devices that prevent the girders 3, 16 from moving are also provided. Then a traveling space can be formed between an upper layer of a lower guide way structure 1 and a lower layer of an upper guide way structure 2 by moving both the girder members 3, 16 and 4, or either of the girder members 3, 16 or 4 in the upward or in the downward direction.

摘要： PURPOSE:To simplify an equipment for switching guide rails between a straight state and curved state according to the reference position and branching position of a branching railway. CONSTITUTION:The guide rails 11 and 12 on both sides of a branching railway D are formed continuously from the start points to end points of the railway and supported by rail supporting devices 15 and 15 at both side sections of each movable beam E in its longitudinal direction. In moving the branching railway D to a branching position, the guide rails 11 and 12 are curved using supporting sections as fulcrums by turning force of the beam E.

摘要： PURPOSE:To reduce various kinds of costs, simplify maintenance and facilitate control of beam movement in the switching of railways. CONSTITUTION:Double track type communication railways C and D comprising a plurality of movable beams 1a... and 1b..., which are arranged in the longitudinal direction of the railways, connected to each other at the ends opposing to each other so as to be able to rotate around vertical shafts Q are provided at the spanning section of double track type fixed railways A and B comprising an up-line and down-line. In these communication railways C and D, the corresponding vertical shafts Q and Q of the up-line and down-line are connected to each other by links 2 to constitute a plurality of parallel link mechanisms between the up-line and down-line of these connecting links 2 and movable beams 1a and 1b.

摘要： PURPOSE:To reduce manufacturing costs, facilitate maintenance and smoothly move railway tracks by simplifying the constitution of a moving device to move a franching railway track. CONSTITUTION:As a means for moving a branching railway track C between a reference position and ranching position, a drive wheel 24 driven by a motor 21 is provided at one side and a driven wheel 25 at the other side interposing the branching track C, and a tractor member 22 is spanned between them to constitute a closed loop body. A control means for the motor 21 determines the deflection between the position of the railway track determined by calculation based on the basic control signal from an operation command section and the position of the railway track detected by a position sensor to determine control amount by adding a feedback signal according to the deflection to the basic control signal only when the deflection exceeds the reference value which is set beforehand.
