The cost of the Joydebpur-Ishwardi rail line expansion project may increase to Tk 26,000 crore, over 80 percent higher than the original estimate, mainly due to long delay in starting work after China decided not to fund the project.

After China abruptly withdrew from its role of financier of the Joydebpur-Ishwardi Double Line Project a couple of years ago, Bangladesh Railway (BR) is now reviving it with Japanese assistance.
