Install seismic retrofits

The road ay and oating ridge ill e seismically retrofitted to prepare the structures for light rail operation

Prepare the work zone

Cre s must clear uildings and soil and prepare the or one for ast in construction cre s This includes erecting arriers and fencing to eep the

or one safe

Install track and power

Sound Transit installs trac and ire hile placing poles and ancillary structures that po er the system and operate the signals

Build station and supporting infrastructure

e t, Sound Transit lays the foundations necessary to run light rail trac and uilds stations and supporting infrastructure

Install and test systems

efore light rail opens to passengers, Sound Transit completes a safety certification process testing communications, safety and emergency systems, as

ell as signals and crossing gates

ast in construction includes uilding at grade, ele ated, and

Pioneering engineering As part of the East Link extension, Sound Transit will do something that’s never been done before—run light rail trains across a oating ridge

To do this, engineers and designers had to consider a number of factors, including six ranges of motion as trains tra el onto the oating portion of the

ridge ere s ho e stepped up to the challenge

The resultsAfter collecting more than 500 channels of data during each light rail vehicle pass, the track bridges passed all critical test criteria with the ability to provide safe and comforta le light rail ser ice at speeds up to mph

Passing the testSound Transit shipped the test bridges and two light rail vehicles to the Transportation Technology Center (TTC) in Pueblo, Colorado, where freight and commuter rail agencies from around the country test ne technologies

At the TTC, Sound Transit was able to mimic the forces and movements the track bridges will experience during normal and extreme conditions, including lake level, sway, roll and surge forces

What did we do?To accommodate running trains from the land ridge to the oating ridge, Sound Transit built two life-size test trac ridges The trac ridges

consist of rails that rest on a series of bearings and plates to let them move with the changing lake levels and ridge mo ements
