Proven, Engineered Retaining Walls for Rail


When it comes to critical railroad infrastructure, only the most technically sound solutions will suffice. Whether your next railway project needs to support a live load, cross a wetland, hold up an embankment, eliminate a switch, or even elevate a track, Redi-Rock can help.

An Ideal Solution for Railroad Retaining Walls


Redi-Rock precast modular block (PMB) products and accessories are made of first-purpose, air-entrained, wetcast concrete that will stand the test of time. The broad range of massive blocks can be used to build gravity, reinforced, freestanding or hybrid walls, and the system is backed up by a wealth of engineering resources and a technical support team to help you tackle your toughest rail projects. With natural stone textures, the solutions look great, too!

New Mexico Department of Transportation used Redi-Rock for a number of bridge abutments and retaining walls as the Rail Runner commuter train line was being constructed to connect Albuquerque and Santa Fe. Read the case study.

A Cobblestone wall replaced a failed stone and mortar wall along railroad tracks

After a 19th century stone and mortar wall failed, causing the private bridge it was supporting to collapse onto an active railroad track, a quick solution was needed. Norfolk Southern worked with JMB Construction and local Redi-Rock supplier Paxton Precast to get a 13.5-foot (4.1-meter) gravity wall installed. Read the case study.

A Metra commuter train goes by with a Limestone retaining wall providing support below

When a crumbling crib wall needed to be replaced along Chicagoland's Metra rail line, the City of Harvey took the opportunity to improve the look of its downtown area as well as replace the aging wall. They chose Redi-Rock Limestone retaining walls for the 3,553-square-foot (330-square-meter) project. Read the case study.

Gravity Walls

In many scenarios, tall gravity walls can be used to simplify rail projects. With no need for tiebacks, the massive PMBs stack up like giant Lego blocks to hold back the earth with their mass. The patented knob and groove technology provides a strong sheer interface connection, as well as makes the proper setback angle easy to achieve. With the easy installation sequence, track closures and downtime can be kept to a minimum!

Reinforced Walls

Reinforced walls designed with Positive Connection (PC) blocks can meet the most demanding structural needs of rail projects, including meeting AASHTO LRFD and AREMA specifications. Strips of geogrid wrap through a core slot cast into the block creating a weight independent connection. Not only can these MSE walls support heavy live loads and reach extreme heights, there's also no need to worry about metal fasteners or reinforcement interacting with stray electrical current.

Freestanding Walls

Redi-Rock Freestanding blocks can create parapet, barrier or force protection options to provide top of wall safety functionality. With texture on two sides, freestanding blocks can be used to create a stand-alone wall or be used with other wall types to complete the integrated wall solutions.

Hybrid Walls

Hybrid solutions are an option with the Redi-Rock system because all wall types can be combined to create integrated wall solutions. Whatever the engineering demands are behind the wall, the face of the wall presents a cohesive solution. Mix and match the wall types you need to get the engineered result you're after for your next rail project.

Canadian National (CN) Railway Project

In 2011, the Canadian National (CN) Railway and the Montreal Metro began construction on a major renovation project. The goal of the project was to eliminate an at-grade crossing where the CN Rail line crossed over the Societe de Transport de Montreal (STM) light commuter Metro line. Take a look at how engineers utilized the Redi-Rock Positive Connection (PC) System's ability to handle massive loads to complete this project.

New Mexico Rail Runner Express Project

When the Rail Runner Express commuter train in New Mexico needed retaining walls and bridge abutments along the rail line, engineers chose the Redi-Rock retaining wall system for it's versatility and proven track record. Read on to see how this project incorporated both Redi-Rock gravity walls and Redi-Rock Positive Connection (PC) System walls to meet the requirements of this railway project.

LDH Energy Rail Yard Renovation

After sitting unused for 30 years, this rail yard needed to be renovated before LDH Energy could begin using it. The yard includes three rail lines that cross over the top of a concrete box culvert flanked by deteriorating wooden cross tie retaining walls that had to be replaced in order to support the rails. Find out why engineers chose the Redi-Rock Positive Connection (PC) System as the best solution for this project.
