The X37 “Swift” service, linking Glasgow and Falkirk, has become a familiar and well-regarded feature of public transport across central Scotland. Operated by McGill’s Bluebird, the route provides a fast, modern express connection between two major urban centres.

Branded under McGill’s striking Swift identity, the X37 is typically worked by Alexander Dennis Enviro400 double-deckers finished in the distinctive Bluebird blue livery. These buses represent the modern face of inter-urban travel, combining high capacity, contemporary design and strong visual presence — making them instantly recognisable on the road.

For Rainbow Railways, the X37 has a particularly close and personal connection. Our retail facilities in Linlithgow sit just moments from the route by jumping on the teh X38 service to Edinburgh.

That local link is exactly why we’re super-happy to be offering a highly detailed Northcord model of this very bus. We currently stock the Northcord UK6547 ADL Enviro400, representing McGill’s Bluebird Swift fleet number 8949 (SN66 WGZ), produced in 1:76 scale to match standard OO gauge layouts and collections.

The model captures the clean lines and modern styling of the real Enviro400, along with accurate Swift branding and Bluebird livery details. It’s an ideal addition for anyone modelling contemporary Scottish transport, building a realistic modern streetscape, or simply wanting a miniature version of a bus that’s a familiar sight across Glasgow, Falkirk and Linlithgow.

There’s something particularly special about stocking a model that represents a service so close to home. Whether you’ve travelled on the X37 yourself or just appreciate modern bus operations, this Northcord release brings a genuine piece of transport beauty in miniature form.
