• Conversion apparatus shall be removed from switch rod
• Steel fitting for prevention of falling down fixing bolt of switch rod to tongue rail shall be removed
• Part shown as Inspection item shall be washed with machine oil • Part shown as inspection item shall be carefully inspected by visual
check.
• Depending on the necessity, color liquid penetrate test (color check) shall be effected.
• Existence of cracks, flaws etc. and extent thereof shall be recorded. • Each part dismantled shall be re-assembled.
(ii) Joint at the loose-heel switch (except flexible switch). • R54 turnouts
a) Washer supporting turnout joint plate shall be removed b) Joint bolts shall be loosened and removed.
c) Turnout joint plate and washers for fastening rail shall be removed
d) Heel block shall be removed
e) Part shown as item for inspection shall be washed with machine oil.
f) Part shown as item for inspection shall be carefully inspected by visual check.
g) Color liquid penetrate test (color check) shall be effected, if considered necessary.
h) Existence of crack, flaw and damage shall be recorded. i) Each part shall be re-assembled.
• R 54 side track turnouts
a) T-shaped bolt shall be loosened and removed. b) Joint bolts shall be loosened and removed.
c) Turnout joint plate, heel block and collars shall be removed. d) Part shown as item for inspection shall be washed with machine
oil.
e) Part shown as item for inspection shall be carefully inspected by visual check
f) Color liquid penetrate test (color check) shall be effected, if considered necessary.
recorded.
h) Each part shall be re-assembled.
• Run-over type turnouts (unbroken main line turnout) a) Joint bolts shall be loosened and removed.
b) Turnout joint plate and collars shall be removed. c) Washers for rail fastening shall be removed.
d) Part shown as item for inspection shall be washed with machine oil.
e) Part shown as item for inspection shall be carefully inspected by visual check.
f) Color liquid penetrate test (color check) shall be effected, if considered necessary.
g) Existence of crack, flaw and damage and extent thereof shall be recorded.
h) Each item shall be re-assembled.
(iii) Others
a) Bolt holes at bottom of tongue rail at the point to which supporting rod is fitted for N turnout shall be inspected in the same manner as switch rod.
b) Flexible part of tongue rail
1. Flexible part to be washed with machine oil. 2. Inspection shall be done by visual check.
3. Color liquid penetrate test (color check) shall be effected, if considered necessary.
4. Existence of crack, flaw and damage and extent thereof shall be recorded.
c) Side face (gauge corner) of toe of tongue rail
1. Tip of tongue rail and its vicinity shall be washed with machine oil.
2. Inspection shall be made visually.
4. Existence of crack, flaw, damage and extent thereof shall be recorded.
d) Rail joints shall be inspected in accordance with the specifications on the detailed inspection of the ordinary track line (Clause 138 hereof).
e) Bolt holes for web of tongue rail
1. Connecting plated for web of tongue rail, bolt holes with steel fitting as washer shall be inspected visually, as they are, that is, without removal of the said attachments.
2. However, should the circumstances require removal, then they shall be removed, and visual inspection or color liquid penetrate test shall be made.
3. Existence of crack, flaw, and damage and extent thereof shall be recorded
c. Omission of dismantling of turnouts
(i) Switch to be borne in mind in omitting dismantling
• Regarding the flexible points such as R54 type inspection through dismantling may be conducted, depending on the necessity.
• Regarding 50N metric turnouts other than 40N metric and 301 type and 251 type (flexible point type), inspection through dismantling may be conducted, depending on the necessity.
• The expression “Depending on the necessity” as referred to in i) and ii) above, means the case where any of the following defects is identified:
a) The extent of non-engagement of the tips of tongue rails has reached as many as 15mm.
b) As a result of visual check or color liquid penetrant test, cracks, flaws, damages are found to the heel block, large-size alcove plates, bolts.
c) Furthermore, improper or poor contact of tounge rail is highly likely. For any other than the said four cases, dismanthling shall, in principle, be omitted.
• Turnouts subjected to “Omission of Dismantling” shall be inspected at the specified interval; regular visual check or color check shall be conducted, instead of inspection through dismantling.
• In carrying-out of inspection through dismantling, heel joint bolts, switch-rod bolts and collars, etc. shall be replaced with new ones. • With regard to 50Nwit and 40N wit, 37kg, 30kg turnouts excepting
261 type, inspection through dismantling shall be conducted.
• With regard to special turnouts such as DSS, SSS, movable DC three-way turnout, double turnout, inspection through dismantling shall be conducted.
(ii) As regards the points for inspection and the method of inspection, the specifications in the preceding items shall apply. Further, the following factors shall be taken into consideration.
• Conditions of Looseness and damage of the bolt and collar at the switch rod fitted point.
• Wear and damage of tongue rail and differences in position of tips of pair tongue rail
• Looseness and damage of bolts at the heel part, and looseness and damage of heel block, damage to large – size alcove plate
(3) Criteria for judgment/assessment a. In case of dismantling of turnout
• Switch rods • Joint bolts • Tongue rails
• Bolt holes for connecting plate (in case of connecting plate being fitted with)
• Bolt hole for switch rod • Large-size alcove plate
(ii) Turnouts with cracks, flaws and damages to heel block, washers, collars and joint plates that will most likely cause adverse effect to proper operation of the turnouts.
b. In case of dismantling being not required:
Regarding the criteria for judgment/assessment, the preceding sub-clauses shall apply. Further, the following factors shall be taken into account.
(i) Conditions of looseness and damage of the bolts and collars at the switch rod -fitted point
(ii) Wear and damage to tongue rail and difference in position of tips of pair tongue rails
(iii) Looseness and damages to bolts at the heel part, looseness and damage to heel block, and damage to large-size alcove plate.
