IN reply to the remarks of Russell Davies (Letters, February 17) on gritter wagons, there are many de-mountable units in Lancashire council yards that are not always cost-effective.

Gritter wagons that are de-mountable run on ordinary diesel so the unit can be used for waste disposal work. Regular gritters run on red diesel, saving a lot in fuel costs.

Also, the council yards cannot keep up with the rot caused by salt. I have seen new gritters become a total loss in two years.
