in 1994, strathclyde police decided to scrap the remaining glasgow police boxes. however, owing to the intervention of the civil defence & emergency service preservation trust and the glasgow building preservation trust, some police boxes were retained and remain today as part of glasgow's architectural heritage. at least four remain—on great western road (at the corner of byres road); buchanan street (at the corner of royal bank place); wilson street (at the intersection of glassford street, completely restored); and one near the corner of cathedral square (at the corner of castle street, also restored). there was also a red police box preserved in the glasgow museum of transport but this was returned to the civil defence trust after glasgow city council decided it did not fit in with the new transport museum. the police boxes in glasgow on great western road, cathedral square, and buchanan street are currently under licence to a glasgow-based coffee outlet. , only the great western road and buchanan street boxes have been transformed to dispense beverages, and restrictions are enforced by the civil defence & emergency service preservation trust to prevent the exterior of the boxes from being modified beyond the trademarked design.
