Recently, lightweight cellular concrete has been used to construct a 40-foot high by 50-foot wide freestanding railroad embankment with vertical sidewalls near Colton, California. The embankment and flyover structures are about 7,000 feet long and consist of 220,000 cubic yards of lightweight cellular concrete. The embankment was designed to support 3 simultaneous Cooper E-80 freight railroad live loads and seismic loading from a 2500-year return period earthquake event. In order to provide an earthquake resilient material, cellular concrete was selected because of its relatively low density (25 to 37 pounds per cubic foot) and high compressive strength (140 to 425 pounds per square inch), when compared with traditional backfill materials. -

For the record, infrastructure is the large-scale public systems, services, and facilities of a region that are necessary to support economic activity and quality of life . The systems that are readily used and noticed by the general public are the highway and public transportation systems, airports, school facilities, and community parks . Other systems of infrastructure that are not readily seen by the public are the underground water, sewer, and utility pipes, flood control systems that protect us from storm water runoff, and solid waste facilities . These are the “unsung heroes” of infrastructure, and are only a concern when they do not work . For example, turning on the faucet and nothing coming out, flushing the toilet and having it back-up, or putting out your trash, and no one picks it up . -

RAIL SYSTEM PLAN December 2018 Table of Contents
2015 FLORIDA RAIL SYSTEM PLAN December 2018 Table of Contents FLORIDA RAIL SYSTEM PLAN - 2018 UPDATE The Florida Department of Transportation (FDOT) Freight and Multimodal Operations Office (FMO) present this 2018 update of the 2015 Florida Rail System Plan. As new challenges have had a great impact on the needs and future projects identified in the 2015 Rail System Plan, FDOT prepared this update. CHALLENGES • New State Rail Plan Guidance was created in 2013 to set a standard format and elaborate on required elements of the plan to include a 5-year update cycle, and a requirement for states seeking capital grants under Sections 301, 302, and 501. See https://www.fra.dot.gov/Page/P0511. Thereafter, FDOT prepared a 2015 Rail System Plan that was completed in December 2015. The Plan was not published at that time, as major industry changes were expected and no public outreach had yet been conducted. • Major industry changes occurred that impacted most of the rail mileage in Florida: o CSX hired Hunter Harrison in spring of 2017, and radically changed the company by imposing precision-scheduled railroading instead of a hub-and-spoke system. This approach has been continued by CSX leadership through 2018. o Grupo México Transportes (GMXT), the leading rail freight transportation company in Mexico, successfully completed the acquisition of Florida East Coast Railway in 2017. o Brightline began service in 2018 between West Palm Beach, Ft. Lauderdale, and Miami later in the year, and with plans to connect to Orlando and potentially to Tampa in the future. APPROACH • The FAST Act (Title 49, Section 22702) passage in December 2015 changed the 5-year update cycle to a 4-year update cycle. -

These are settlements based on the ethos of ‘Garden Cities’ promoted by the Town and Country Planning Association (https://www.tcpa.org.uk/garden-city-principles) and Government but tailored to the needs and character of North Essex. AECOM has undertaken a detailed baseline review and multi-criteria analysis of various options, identifying three broad locations at West of Braintree, Marks Tey and East of Colchester in Tendring District for further master planning (https://www.braintree.gov.uk/info/200130/about_braintree_district/992/north_essex_garden_communities). These locations are considered to be the most sustainable option for the future development of Garden Communities in North Essex and provide a major opportunity for high quality, cohesive and distinctive mixed use development. -

Conducting a Grade Separation for Colton Crossing the Story
THE INTERSECTOR CASE STUDY INTERSECT R PROJECT I 2 Conducting a Grade Separation for Colton Crossing Issue: Infrastructure | Location: California, United States The Story Colton Crossing, in Southern California’s San Bernardino County, is one of the busiest railway junctions in the US, serving as many as 120 trains per day. In addition to the Crossing’s two intersecting tracks, the Burlington Northern Santa Fe Railway (BNSF) north/south track and the Union Pacific Railroad (UPRR) east/west track, the Metrolink and Amtrak commuter lines all use the junction, requiring trains to idle at the crossing for over 50 minutes on average and up to four hours. Railway traffic was projected to double by 2020. A grade separation – a bridge that disjoins overlapping rail lines – would allow for more commuter and cargo trains to pass through Colton at faster speeds, and would reduce air pollution caused by idling trains. Individually, the California Department of Transportation (Caltrans), the City of Colton, private railways, and commuter lines were unable to shoulder the cost of constructing a grade separation, and their divergent interests prevented them from working together. Garry Cohoe, Director of Project Delivery for the San Bernardino Associated Governments (SANBAG), was called on to develop a plan and to guide a collaborative effort between the multiple stakeholders. Garry was able not only to bring together the various stakeholders, but also get the residents of Colton behind the plan, dividing the costs of construction and responding to -
