a. Maintenance of its performance
Status of maintenance shall be inspected visually, and instruments and tools such as space gauge may be used, depending upon the necessity.
i) Close contact of tongue rail
Extent of close contact between tongue rail and stock rail within the distance of 500 mm from the edge of tongue rail shall be measured by thickness gauge, etc.
ii) Contact of tongue rails
Contact between tongue rail and stock rail in the section other than those of close contact shall be measured by thickness gauge etc.
iii) Position slide and engagement shape of toe of tongue rails
Position slide and engagement shape of tongue rails shall be measured by angled ruler or folding scale.
iv) Flow
Extent of flow of tongue rail and stock rail in the section where the top parts of them stay in touch with each other, shall be measured.
v) Width of flange-way
Width of flange-way between crossing and guard shall be measured.
vi) Flow of nose and guard
Flow shall be measured visually or by use of scales, etc.
vii) Looseness of equipment and accessories of fastening, spacing and oiling conditions thereof:
They shall be checked / inspected visually or by use of measuring apparatus. The detailed method shall be as per the followings:
• Space between bolt for heel joint of the switch and the joint plate supporting device, shall be inspected.
• Space between the edge of switch rod and the projected part of connecting plate, shall be inspected.
• Right angle irregularity to bolt for heel joint of the switch shall be inspected.
• Mismatch on the tread, mismatch on the gauge at heel joint of the switch shall be inspected.
• Status of joint gap and flow at heel joint of the switch shall be inspected. • Torque of fastening bolts for switch rod and bolts for heel joint of the
a) Oiling status
b) Gap with tongue rail • Spacing of point guards, flow
They shall be inspected visually or by use of measuring tools. b. Conditions on materials
i) Wear, damage and erosion of the tip of Switch • Wear of the toe of Point
a) With regard to R 54 turnout, 60 kg rail turnout, the position with the width of the tongue rail top part of 6mm and that of 10mm (14mm in case of 60kg rail No.8 turnout) shall be marked respectively, at which points, the width of the top shall be measured.
b) Regarding the turnouts designed in 1925, the maximum wear at the point of 500mm and 1000mm from the tip of the tongue rail, respectively shall be measured.
c) In stock rail, at the point 10mm in front of the front edge of tongue rail in gauge line, amount of wear of the side face shall be measured.
• Minus of part of tongue rail
a) In case that loss is continued from the tip of tongue rail (including the case that the original material is lost in upper area of the track gauge line under 14 mm from the top of stock rail, from that loss towards the tip of the tongue rail), a and b (height and width of a defect) shall be judged/ measured.
b) Should the loss exist in the middle of part tongue rail, not only a and b, but also L (length of a defect) shall be measured.
c) Should the results of (1) and (2) prove that the loss should be replace with new rail, it shall be checked/inspected by wear measuring gauge, etc., as to whether the angle point of the lost part is positioned higher or lower that of the corner of the gauge. • Shape of tongue rail and its engagement position
a) Status of engagement of stock rail and tongue rail and the tread of flange-way at the top of tongue rail shall be visually inspected. b) In stock rail, at the point of 10mm in front of the front edge of
tongue rail in gauge line, amount of wear of the side face shall be measured.
ii) Wear, damage and erosion of part other than toe of point
• They shall be measured visually or by use of measuring tools.
• Height of wear means the point showing the maximum height to be measured right angled to the wear face.
• Tongue rail wear measuring position
Original Width of top
20mm 30mm 40mm Rail cross section
• Crossing
Height of wear means the position showing the maximum height of wear to be measured right angled to the wear face. However, the measurement shall be made right angled at the top surface of the recess of the crossing. In case of wing rail risen K-type crossing, the measurement shall be done according to the specifications of itself. • Guards
The part correspondence to recesses near crossing nose-edge, movable crossing and its closely contacted points shall be measured.
Furthermore, for the purpose of more effective anti-wear, additional measurement to the parts shall be carried out.
• Rail in turnouts
Height of wear shall be measured right angled to the wear face. (3) Criteria for judgment/assessment.
a. Status of Maintenance to properly keep Operation i) Close contact of tongue rail
Space between tongue rail and stock rail at the tip of the tongue rail, shall be kept within 1mm.
ii) Contact of tongue rail
Gap between tongue rail and stock rail other than the close contact referred to in a above, shall be kept within the following allowances.
54R High speed turnout R60 kg rail turnout
High speed turnout (120km/ h)
3 mm •
• The allowances for turnouts under 120 km/h speed shall be 4mm, and side track turnouts shall be 5mm respectively.
iii) Position slide of tongue rail
Extent of more than 15mm position slide shall be rectified. iv) Flow
Flow most likely causing adverse effect to proper close contact and conversion of tongue rail shall be rectified.
v) Width of Flange-way
Such width of flange way obstructive to the lower part construction, gauge shall be rectified. In high speed turnouts, the width of the flange- way adjacent to both edge of guard rails (cross-section changing point) shall be kept over 56 mm
vi) Flow of noses and guards
Flow having reached 1mm shall be rectified.
vii) Looseness of equipment and accessories of fastening, and status of spacing and oiling:
• Bolts for heel joint of switch and the joint plate/supporting device, shall be not contact.
• Space between the switch rod of the close contact side and the projected part of connecting plate has developed by more than 1mm, shall be repaired.
• Considerable right angle inclination/ deviation to bolt for heel joint of switch shall be repaired.
• Considerable tread and gauge mismach of 1.5 mm difference of heel joints of switch shall be repaired. Also shall the high speed (120km/h or more) turnouts with more than 1mm gauge mismach be repaired. • Considerable joint gap of heel joint of switch shall be repaired. Flow at heel joint of switch developed enough to create adverse effect to proper conversion of tongue rail shall also be repaired.
• Those of loose tightening of bolts for switch rod and bolts for heel joint of switch and tightening too excessive against proper conversion of switch shall be rectified.
• Base plate that needs oiling shall be properly oiled.
