Sodor Suspension Bridge (T&F)/Behind the Scenes

Television Series
The Sodor Suspension Bridge is a fictional bridge near Wellsworth on the Island of Sodor created by Paul Larson and Marc Seal.

Gauge 1 models
The Sodor Suspension Bridge was originally built for the 2005 film Calling All Engines! It had three models; one was painted rusty, the second was built to collapse and third was painted green.

CGI model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. The Sodor Suspension Bridge was recreated from scratch in CGI by Nitrogen Studios. The model was "hand-sculpted" in Maya, a 3D animation and modelling software.

According to Greg Tiernan, the CGI models are subjected to many rounds of review before they are submitted to HiT Entertainment for final input and approval.
