1204 Classification of ODC consignment :

ODCs are divided into 3 classes according to the minimum clearance available between theconsignment and minimum fixed structure profile.

Class ‘A’: Those ODC loads, which have a gross clearance of 22.86 cm (9 inches) andabove and net clearance of not less than 15.24 cm (6 inches) from the fixedstructure all round but which nevertheless infringes the standard movingdimensions.

Class ‘B’: Those ODC loads, which have a gross clearance of 15.24 cm (6 inches) andabove, but less than 22.86 cm (9 inches), and a net clearance of not less than7.62 cm (3 inches) but less than 15.24 cm (6 inches) from the fixed structure.

Class ‘C’: Those ODC loads, which have a gross clearance of less than 15.24 cm (6inches) but not less than 10.16 cm (4 inches) and net clearance of less than7.62 cm (3 inches) but not less than 2.54 cm(1 inch) from the fixed structure.

Note: (i) Gross clearance means the extent of clearance when the consignment isstationary.

(ii) Net clearance means the extent of clearance after allowing for horizontal lurchingand vertical bouncing.

Net Clearance :

The net clearance shall be worked out as under :The net clearance between the consignment as loaded in the train and any fixed structureshould be calculated after making an allowance of 75 mm (3 inches) for lurch (horizontal)and 7.62 cm (3 inches) bounce (vertical) on the straight together with following additionalfactors applicable only when the structure in question is situated on a curve.

1. Horizontal Clearance :(a) Allowance for lean due to super-elevation and over hang due to curvature.

The lean should be calculated for that point on the profile of the load which is likelyto have the smallest clearance from fixed structure the formula being :-

HC G

where H = height in feet to the point being considered. C = Super elevation G = gauge.

For the central overhang due to curvature, the formula will be :- B2 8R

where B = distance between bogie centre R = Radius of curve.

In cases where the overhang at the end of a vehicle may have to be calculated bythe formula will be :- L2-B2

8Rwhere L is the length of the vehicle.

(b) Additional lurch on curves may be taken 38 mm.

2. Vertical clearance :In case where the top width of the consignment exceeds the gauge of the track thevertical tilt should be added to the height of consignment to work out the vertical clearancefrom the fixed structure.

1205 Procedure for sanctioning movement of ODC :

When ODC consignment is offered at a station for booking SS/SM will verify if the consignmentexceeds the maximum moving dimensions from originating station to destination stationincluding via. and break of gauge, if involved. He should apply to the Sr.DOM, who willobtain the necessary sanction of the competent authority.

An application must show the length, width, height, and weight of the load accompanied bya sketch in duplicate of the consignment.

In communicating sanction for the movement of ODC, specific route, through which theparticular consignment will move, should be indicated, and it will be the responsibility of theSS/SM of the station from which the load originates.

In addition to strictly adhering to the specific route, the restrictions (eg. speed restrictions,night running restrictions, platform restrictions etc.) notified for conveyance of the consignmentover the route, must be adhered to, and no relaxation in this regard is permitted.

1206 Loading :On receipt of the sanction, the consignment should be loaded carefully, lashed and packedproperly, so as to avoid any change of shifting enroute.

While examining the wagon loaded, the SE(C&W) must pay attention on the following:1. Load is well secured;2. Load is within the C.C. of the wagon;3. Weight on any pair of wheels does not exceed;4. Axle load restriction, if any;5. Under gear of the wagon.

After loading the consignment, Sr. SE(C&W) will register the measurement and advise theSS/SM concerned of the various overall dimensions, including the packing and lashing etc.,as loaded in truck. SE(C&W) must issue “fit to run” certificate to the effect that the loadedwagon concerned is safe to run via the particular route specified.

SS/SM will inform, then to Sr.DOM/DOM and office of the COM, followed by a confirmationcopy, to be sent to COM.

The Operating Branch will arrange to advise the COM of the other Rlys. concerned, with fulldimensions of the consignment, as loaded in the truck for issue of necessary final sanctionfor movement.

Under any circumstance, provisional sanction must not be treated as final sanction and finalsanction must invariably be awaited before consignment is despatched.

SS/SM/YS/YM concerned must furnish full particulars of the wagon to the Control, such asWagon No., Owning Rly., Type of Wagon, Station from and to, route over which it is requiredto move etc. After this, Control/Divisional office will give necessary permission to the concernedstaff to despatch the wagon by a particular train on date advise and obtain theiracknowledgement.

A Caution Order will be given to the Guard and Loco Pilot of the train carrying ODC to restrictthe speed and observe any other speed restriction at any other point or other precautions aslaid down.

On Electrified Sections :

In addition to the precautions laid down above, the following special precautions must beobserved for transport of over- dimensional loads on the electrified section:


71

1. In all cases, where oversize consignment is moving, it should be remembered by all staffaccompanying the ODC, that the overhead electrical equipment is always ‘LIVE’, exceptwhen a particular power block has been obtained from the Traction Power Controller.Even when a power block has been obtained, it should be remembered that all the lines,other than those for which the power block has been granted, are ‘LIVE’ at 25000 Volts.

2. No person should climb on the roof of carriages of wagons, when those vehicles arelocated beneath the overhead equipment, except when the equipment is made ‘DEAD’and earthed.

3. The following are the prescribed clearance from contact wires for the passage of over-dimensional loads through electrified traction areas and the special restrictions required:(a) Special speed restriction is not required when the gross clearance is at least 390

mm.(b) Speed must be restricted to 15 kmph, when the gross clearance is in between 390

mm to 340 mm.(c) Speed must be restricted to 15 kmph and over head power must be switched off

when the gross clearance is less than 38 mm.

4. No consignment with less than 100 mm gross clearance from the over head contact wirewill be permitted over electrified section.

5. A representative of the Traction Department should also accompany all ODC havingclearance as specified in item (b) and (c) of sub para (3) above, over electrified section.

6. A representative of the Traction Department should accompany all ODC loads havingwidth of more than 1981 mm for BG and 1910 mm for MG from the centre line of thetrack.

7. Section Controllers and Traction Power Controller must co-ordinate, while an ODC moveson electrified area.

8. A list of structures, where the clearances are restricted on the electric traction area andalso the clearance available under overbridges should be with the Section Controllersand Traction Power Controllers.

1207 Despatch :

1. At the originating station the ODC wagon will be moved when final approval has beenobtained from the competent authority.

2. At the originating point the number of wagon/wagons carrying ODC should be entered bythe Train Clerk/SM in the vehicle guidance in red ink to be handed over to the Guard ofthe train.

3. SS/SM should advise the Section Controller on duty, before starting the train and whileasking line clear, describe the train number with letter ‘X’ suffixed on it.

4. It will be the duty of the Dy.Chief Controller to keep adjoining Control Office informedabout the movement of such ODC, till such time, it is handed over to the adjoining divisionby specified train. Also ensure that the consignment is moved strictly by the authorisedroute.

5. Shunting of train with an ODC should be avoided. Loose and rough shunting of ODCwagon and against such wagon is prohibited.

6. When any ODC wagon is detached from the train at any station, SM and Guard areresponsible to ensure safe placement and securing of wagon/load.


72

7 Facility for accompanying staff for extra wagon/brake van should be provided if so required.

8 (a) When a load is so long that it cannot be accommodated in two trucks (i.e. two 8wheelers), it must be loaded in three trucks so that the entire weight is carried onthe centre vehicle and the end trucks are idlers. The load must be placed on packingin the centre truck, so that it is clear of the floor of the end trucks by not less 152 mmand there must not be less than 304 mm up side clearance in the end trucksbetween each of load and side of truck.

(b) If the weight of the load is such that it cannot be carried on the centre truck, then theload must be carried as equally as possible on the trucks and the centre vehiclemust be an idler.
