Marmaray TBM Scale Model

About the Marmaray TBM Scale Model

A Marmaray TBM Scale Model reveals a piece of engineering most people never see: the tunnel boring machine that worked underground on one of Istanbul’s most important rail projects. In the Marmaray project, the land tunnels were excavated with tunnel boring machines (TBMs), while the Bosphorus crossing was built as an immersed tube tunnel. The project created a continuous rail link between Istanbul’s two sides.

Explaining how a TBM works in words is difficult; a scale model makes it clear in seconds. MiniatureArt’s Marmaray TBM model shows the tunnel boring machine’s cutter head and body components at scale. Viewers can see how the machine advances behind the rotating face that cuts through the ground, and how the tunnel takes shape behind it.

For engineering models, MiniatureArt uses durable polyurethane and resin parts and pays close attention to hand painting that conveys the character of metal surfaces. Where needed, lighting or cut-away openings can highlight internal mechanisms. Models like this are highly effective at construction and engineering fairs, in technical training, in science museums and in project presentations. To learn about the machine type itself, read more about tunnel boring machines on Wikipedia.

If you are curious about the undersea section of the project, our Immersed Tunnel Cross-section Model page explains the internal structure of the tube beneath the Bosphorus and how it differs from the bored land tunnels.

MiniatureArt delivers high quality results at affordable cost, even on projects that demand technical accuracy, and we stand behind the work we deliver.
