4. Why ‘BTFLN Wagon’ chosen for the Award
• Indian Railways awarded the ‘BTFLN’ Wagon Manufacturing Contract
only to M/s Braithwaite & Co. Limited based on BCL’s past performance.
• The manufacturing of PROTO Wagon was a very challenging task as this
was designed for the first time. Lot of trial assembly and subsequent
changes in fitment of components took place during Proto wagon
manufacturing stage.
• Finally BCL manufactured the wagon after modification of brake
arrangement drawing & incorporation of fabricated T-Section which
were approved by RITES and RDSO.
• This Frameless Wagon is a new breed of petroleum carrier tank wagon
designed with advanced features in comparison to conventional BTPN
Type Tank Wagon.
• The company has successfully manufactured 250 Wagons, as per
Contract Terms maintaining cost, quality & time and these wagons are
running successfully on Railway track.

6. HYDRAULIC TEST OF BARREL
The barrel complete with internal fittings
including Master Valve & Bottom discharge
Valve after being mounted on the under
frame shall be tested HYDROSTATICALLY
to pressure 2.8 Kg / cm. sq. against
leakage of longitudinal and circumferential
weld seams of Barrel along with fitted
valves.
The pressure is maintained for 30 Minutes
(min.).
7. A BREAK THROUGH TECHNOLOGY
The newly designed tank barrel is inclined at 1
deg towards discharge points to facilitate easy
flow of POL Products.
8. The wagon is manufactured from:
◦ SAILMA 350
◦ IS: 8500 Fe 570B
These high strength micro alloyed steels have higher
yield strength, higher notch toughness, good fatigue
properties, excellent weld ability and good formability.
9. HUCK BOLT –
FASTENING SYSTEM
Heavy duty applications demand
tough, reliable fasteners. For application
ranging from RAIL WAGON to MINING
EQUIPMENT, HUCK BOLT fastening system
offers superior vibration resistance and
overall durability.
Low cost fastening system.
Extraordinarily low installation time.
Safe, Worker friendly & above all
Environment Friendly.
