ScotRail envisage this requiring the removal of the canister from the vehicle and a change to the air entry point, via some permanent modification and then refitting by SRT staff. In addition we envisage new filters and require a new single piece induction hose connecting the canister outlet to the turbo inlet. Exchanging canisters on vehicle will be performed by SRT staff and is outside the scope of this procurement.
