RAILTRACK THIS week pledged to improve its labour supply vetting system after some labour contractors complained of being suspended from approved lists without explanation.
Railtrack has a stringent vetting process to ensure suppliers provide fully trained staff to railway contractors.
In addition to regular audits Railtrack carries out flash or 'comfort audits' where inspectors demand detailed information about track staff.
If this is unavailable suppliers may be suspended.
They are often told of this in a standard letter giving no explanation.
As a result some have lost labour contracts worth hundreds of thousands of pounds.
Railtrack last week told a meeting of the Association of On Track Labour Suppliers (AOTLS) that in future letters would explain suspensions and how to get them lifted.
Raitrack has been forced to act because of an escalation in the number of labour contractors moving into the lucrative rail market.
