Turbo Power Systems, an AIM-listed engineering firm, has received a spare parts purchase order from Bombardier Transportation to be fulfilled this year and next. The $3.2m order forms part of a $14.2m contract to supply the Chicago Transit Authority with auxiliary power units for its new fleet of metro subway cars. Chief Executive of Turbo Power Systems, Carlos Neves, said: "This important order builds upon our original contract some five years ago to supply Bombardier Transportation with auxiliary power units for the Chicago Transit Authority's fleet of metro subway cars, in what was then our largest single rail order. We have since supplied over 300 units under this contract. "We are delighted to extend our relationship with Bombardier Transportation through this new order."NR
