60 NOS. BOXN WAGON WITH SLIDING ROOF
Railway Board decided that a special purpose BOXN wagon be developed in consultation
with Indian Wagon Builders, which should have a sliding roof cover, and accordingly an order
on trial basis for a lot of 60 wagons was placed on Texmaco Ltd., Calcutta. These 60 wagons are
expected to be commissioned in April, 1989, for a closed circuit service trial to study actual
behavior for loading coal from one side on Eastern Rly to a Cement Plant on South Eastern Rly
and in return to be loaded with cement bags with the sliding roof covering over them.
Board technical specifications required use of the existing BOXN wagons with same
Underframe, Bolster, Casnub Bogie, Air Brake system, etc., but suitably modified to have a light
weigh cover construction such that while uncovering the wagon, the roof could be rolled around
a drum fixed integrally as part at one end of wagon. The operation gears of the covering would
be fitted with self-lubricating bearings for smooth operation.
Light weight galvanised rolling shutters of trough type construction have been adopted
with a simple arrangement for pulling in one direction with the help of chain sprockets and
rolling on a drum in the other direction also with chain sprockets. Changes in top copying angle
and the ends have been made in such a way that the essential features of wagon and its overall
dimensions remain unaffected.
Such type of dual service behavior is being brought in to use on Indian Railway on a trial
basis for the first time because wagons with sliding roof covering are not being used on any
International Railway for bulk transport of coal to be mechanically loaded by chute and unloaded
Such simple mechanism calls for special precautions during use, which should be strictly
observed during the loading / unloading and also during maintenance of the wagon .
On actual study of the defects arising during these functional service trials, adoption of
such type of wagon with necessary modifications could be put in to regular service in future for
bulk transportation. Hence, the following are to be strictly carried out as obligatory functions
during loading and maintenance in between operational use. These are in addition to the other
routine checks specified for the standard BOXN Wagons .

CAUTION AGAINST PILFERAGE
Check after every turnaround that the following items are not pilfered from the wagon.
1. Lath section of shutters.
2 Wire rope.
3. Hand wheel for operation.
CLEANING OF WAGON AFTER COAL HANDLING
After shipment of coal and subsequent delivery at site the wagon is to be cleaned by air /
water jet . The cleaning of the end and side grooves is most essential to ensure that there is no
foreign matter in these grooves, which may hinder the smooth operation of shutter or may even
damage the shutter.
Since the BOXN wagons with sliding roof are being put in to operation for the first time
on trial basis , it is recommended that the persons to operate the wagon should be given prior
proper training in the method of opening and closing of the shutters as outlined below :
WHEN USED AS OPEN WAGON FOR LOADING COAL :
Before loading coal, please check that the Sliding Roof shutter is fully moved inside the
cage . If not:-
A. TO OPEN CHECK
1. If yellow pointer indicating shutter fully “closed” is visible at the drum side Body
End , check if “Lock rod “ at drum side is “ unlocked “.
2. If not, pull it down and “ unlock “.
3. Lock- rod at Shutter end is “Unlocked “.
4. If not, pull it down and “Unlock “.
5. The shutter has been designed to be operated by one man . However , since the
length is 10 Metres long, one man gets tired quickly , as such It is suggested to
use one person at each side on cage of the wagon . These two persons should
retate the hand - wheel in unison as indicated on the wagon side till the shutter is
fully housed inside the cage.
6. Lock shutter in this position by lifting lock-rod. This is to prevent accidental
opening of shutter.
7. In such ‘ Open’ condition, bulk material such as coal / ore is to be loaded and
Opening of the shutter when “locked” MUST NOT BE ATTEMPED ,as this may damage
the lock-rod , the shutter , and may even break the chain .
WHEN USED AS COVERED WAGON
FOR LOADINGCEMENT / GRAIN;
After loading of cement / grains , etc., in bags , the shutter is to be closed over the
wagons, for which the following procedure to be adopted step by step.
B. TO CLOSE SHUTTER OVER ROOF, CHECK:
1 Unlock the locking arrangement at the cage side by lowering the rod.
2. Place one person on each side of wagon at Drum end, and rotate hand-wheel as indicated
on the side of the wagon.
3. Two persons are to rotate hand-wheel in unison, as printed on wagon. The pulling is to
be done slowly and gradually till the shutter covers the wagon.
4. It is observed that when the shutter is about 1meter or so from the fully closed position,
the effort required is increased due to the long length of the shutter. At this time if the
hand-wheel on the cage end is also unwound simultaneously, the closing of the shutter
becomes much easier.
5. Lift the locking rod and close the shutter to “lock” at Drum end.
6. N O T E:-
Although the shutter is treated with sealant against ingress of water, a thin
polythene sheet may be spread on top of cement bags prior to the closing of the shutter as
a matter of added precaution.
MAINTENANCE MANUAL AND INSTRUCTIONS
After the coal has been carried to destination and unloaded , the wagon is to be cleaned
thoroughly , if possible by Air / jet . The cleaning is particularly called for in the groove and the
sliding bar at the top coping angle by wire brushing to ensure that no dust or large pieces of coal
are stuck in coping angle, which are to be removed by hand, if necessary.
Shutter is not to be opened until such time all foreign material which may hinder the
smooth opening of the shutter are removed from the groove.
THIS CHECK IS A MUST.
IMPORTANT CHECKS BEFORE OPERATION:
a) Check the grooves at top coping and ascertain that the grooves are free from lumps, grits
etc. If not clean it by wire brush, hand etc.
b) Though self lubricated bearings provided, chain and sprockets should be kept lubricated
from time to time .
C) Periodically check if the ropes are damaged or not. If damaged, the rope is to be replaced.
d) Check whether the roller chain is taut. If not remove one link and refix chain with half
link to make the chain taut.
e) Check whether the ropes are dry. If dry, put cardium compound on ropes.
f) Check that the groove at top coping and the longitudinal pipe support does not have Any
oily material sticking to it.
g) While loading perishable goods, in bags, the lowest most layer should be kept atleast
50/60 mm above the floor plate level ( with the help of sleeper corrugated sheets etc.) as a
matter or precaution against any water seeping through the side doors , and wetting the
CHECK EVERY THREE MONTHS:
a) Chain for slackness. If slack remove a link and make chain taut again.
b) Wear of self-lubricating Bushes. If spindle shaft is loose, replace the self-lubricating
c) If any damage on sprocket teeth, replace the same.
d) If any wear on sprocket teeth , replace sprocket.
e) If any distortion on lath section of shutter, straighten it.
f) If any damage to lath lugs / Guide, repair same.
g) If any components are found loose or damaged, replace it by good new components.
h) Check for leakage from roof and if any, repair same with local application of
L U B R I C A T I O N:
a) All ‘CASTLON ‘Bushes are self-lubricating type and not be lubricated.
b) All ‘SINTERED BRONZE’ Bushes are self-lubricated and need not to be lubricated at
c) All roller chains are to be kept lubricated with SERVOCOAT 140 every three months.
d) Oil should be applied over the fully coiled Rope on the Drum every three month.
SOME IMPORTANT REPAIR PROCEDURES:
A To make the chain taut:
1. Remove the fasteners at the joining point by nose plier.
2. Remove the pin ‘B’ of any near by link and remove the link ‘C’.
3. Insert offset link ‘D’ in place of standard link, check whether it is still loose , if so
remove standard link ‘C’ completely.
4. Join the end by fasteners and check the chain taut.
B PROCEDURE FOR APPLICATION OF POLYSULPHIDE SEALANT
The Joints at the lath sections of the Sliding roofs of the BOXN wagons have been treated
with polysulphide sealant ( RDL 840 ) manufactured by Messers . Choksey Chemicals Pvt. Ltd.,
111, industrial Area, SION Bombay –400022 to give leak-proof service. Should however, any
leak develop after use at any point , check sealant for cracks , cuts, abrasion etc. If found
damaged, repair as follows:
1. Remove damaged sealant from the joint at the lath section and clean the area. If damage
is extensive, it is recommended to remove sealant from the full 3-Meter width of the
2 Apply RDL 947 primer manufactured by M/s. Choksey Chemicals Pvt. Ltd. on the
3 Mix the 2 component i. e. Polysulphide sealant RDL 840 as base compound with the
accelerator provide by the manufacture.
4. Apply the mix-compound by means of spatula at the joint surface , by pushing the
compound into the joint .
5. After filling the joint completely by pressing spatula moving along the length of joint,
remove air bubbles, if any. This will also place the sealant firmly in the joint.
6. After application of sealant allow it to cure for at least 4/5 days.
The shutter must not be operated after application of sealant for 4/5 days till it is cured
otherwise leak may develop.
C PROCEDURE FOR REPLACING DAMAGED LATH SECTION IF ANY:
A few extra lath sections have been provided in the total length of the roof shutter.
Therefore, removal of one or two laths sections ordinarily shall not need a replacement.
However, if more shutters are required to be replaced then a fresh lath section may be
introduced .However , to replace / repair a damaged lath section :-
1. Mark the damaged lath section.
2. Roll the roof shutter completely inside the cage.
3. Remove the top plate and side cover of the cage.
4. Put a sling around the completely rolled- in shutter, and hold the same with a lifting
5. Remove the bolts at both sides of the cage to free the roller shutter drum from the cage.
6 Lift the roller shutter and the cage with the help of lifting device.
7 Unroll the complete roller shutter on a flat level surface of size about 4 meters X 12
8. Cut the 3 rivets of the end cleat at one end of the damage lath section (see FIGURE)
9. Remove the sealant from both sides of the damaged lath section.
10 Pull out the damaged lath from the end where the end cleat is not removed.
11 Insert a new / fresh lath section into the roof shutter at the place from where The
damaged lath is removed .
12 Fix end cleat to the lath by driving 3 rivets.
13 Roll the entire roof lath and the same into its cage from which it was removed Lift bolt
and replace cover plates and rebolts the same.
14 Refix all pulling / rolling gear as per original arrangement.
15 Apply sealant.
