Turnouts and Crossing Trackwork

Turnouts, crossovers and double crossovers are available in the following sizes:#6, #7, #11, #14, #15, #20, #24 and #30

Formations

Tie spacing: Ties are spaced 30” on center between switch and frog and at least 24” or greater in the switch and frog. This reduces the number of ties in a typical turnout by approximately 25% and less ties require fewer special trackwork plates and reduces the installation cost.

REMOTE MONITORING IMPROVES CONCRETE TIE LIFE CYCLE MANAGEMENT

CXT RFID Tracker Concrete Tie

L.B. Foster is casting an integrated circuit chip into a specialized CXT concrete tie to provide Radio Frequency Identification (RFID) of their product for remote monitoring applications. All associated component attributes are easily retrievable in real time, enabling more efficient supply chain and product life cycle management. This remote system track a tie’s location from manufacturing through customer inventory to track installation.

A remote search by product type, serial number or specification will return a geographic location of each tie with GPS coordinates. The search can determine tie type, reinforcement characteristics, customer and internal specifications, fastening components, material composition and part drawings.

The CXT RFID Tracker is a passive transponder and chip cast into the top surface of the concrete tie under approximately one-eighth inch of grout cover. The chip is embedded in a polymer laminate that is waterproof, shock and impact resistant, and UV protected. It has memory retention of 50 years and features an optical barcode and human-readable backup. The RFID Tracker has an operating temperature range of -50 C to +85 C.

Each time the RFID tie is scanned, information such as, date, time, user ID, and GPS coordinates are uploaded to a database via a wireless network or Wi-Fi internet connection and associated to the tie’s unique serial number. Online map indicators present GPS coordinates of a product search query and provide detailed product information for the user.

Data capture in the plant is via mobile handheld devices, such as Apple iPads. Personnel can easily retrieve relevant drawings and specification documentation from the engineering database. In track, automated RFID readers are attached to rail mounted equipment. CXT’s RFID Tracker will increase the railroads’ productivity by improving communication between all the players in the product life cycle.

Industrial and Port Facility Track Structures CXT® CONCRETE TIES ADD SUSTAINABILITY AND LESSEN COST FOR INDUSTRIAL AND PORT PROJECTS

For more than two decades L.B. Foster has worked closely with owners and engineering firms to standardize CXT concrete tie design that is environmentally-sound, economically-effective and provides proven life cycle cost benefits.

Our CXT industrial ties offer solutions that save time and money while providing a better track structure compared to that of wood or steel ties. CXT concrete ties also have the flexibility to be customized to meet our customers specific requirements.

CXT concrete ties can provide an estimated cost savings of 10% to 15% when compared to timber ties using conventional track construction methods. When mechanized track laying systems are used, the CXT expense can be as much a 20% to 30% lower than wood ties. Life cycle maintenance expenses for concrete ties are also lower than wood tires.

Our concrete ties are more environmentally-friendly than wood ties. Greenhouse gas emissions associated with the manufacture and life cycle of concrete ties appear to be less than those produced by timber ties. CXT concrete ties also require no toxic preservatives and avoid the disposal issue associated with treated timber ties removed from service.

CXT fully pre-stressed concrete ties have a minimum

length of 8’3’’, weigh 600 pounds or less and can be

spaced up to 28” centers provided there is a minimum

ballast section of 8” below the tie. CXT concrete ties

have been used on major West Coast and Columbia

River port projects, food processing plants, oil

refineries, cement plants, landfills, wood processing

plants, intermodal facilities, coal fire generation plants,

ethanol plants, and coal and ore mines.

Sustainable CXT® Concrete Tie TechnologyCXT Concrete Ties offer a sustainable alternative to other types of ties currently used in the North American rail industry. Concrete ties provide superior environmental and energy benefits in their manufacturing and use.

ENVIRONMENTALLY FRIENDLY PRODUCT DESIGN

• Concrete ties are not treated with any chemi-cals that have the possibility of leaching into the ground.

• The steel clips, castings and inserts, as well as steel wire reinforcement, are manufactured using up-wards of 90% recycled scrap steel.

• Concrete ties can be crushed and all components can be recycled.

1. Produced with environmentally friendly concrete.

• No creosote or residue

• Lower carbon footprint compared to wood

2. Castings, clips and inserts are made from recycled scrap steel.

3. Reinforcing steel wires are made from recycled scrap steel.REDUCED GREENHOUSE GAS (GHG) EMISSIONS

• The manufacturing and use of concrete ties can result in one-half to as little as one-sixth the amount of GHG emissions associated with the use of wood ties over their expected life.

• A variety of factors provide this advantage:• Depletion of critical natural resources• Greater track strength (requiring fewer ties per

length of track)• Mining and use of raw materials to produce

concrete ties vs. timber harvesting• Lower maintenance requirements

Energy Savings

• Track constructed using concrete ties is stiffer, providing a higher track modulus.

• Higher track modulus results in reduced rolling resistance.

• Reduced rolling resistance allows railroads to improve their fuel efficiency.

• Up to a 7% reduction in rolling resistance provides a 1.2% to 4.5% reduction in fuel consumption.

OUR COMMITMENT TO SUSTAINABILITY

• Minimize the use of natural gas to heat production beds through increased utilization of ambient conditions. Investigate the use of biofuels in manufacturing.

• Conserve lighting needs through the use of high efficiency lighting to illuminate facilities.

• Minimize contaminants in waste water by increased use of filter presses.

• Minimize hazardous waste by controlling the use of toxic chemicals during manufacturing and investigate the use of other alternative chemicals.

• Reduce electrical demand by installing high efficiency motors.

• Establish a “Go Green” committee to focus on developing and implementing new sustainability initiatives.

All components of CXT Concrete Ties are recyclable.
