The Alaska Railroad (ARRC) will demonstrate the transport of liquefied natural gas (LNG) in intermodal LNG ISO containers from southcentral to interior Alaska during a month-long operational performance project in early fall 2016. ARRC is the first railroad in the country to obtain permission to haul LNG by rail.
The LNG ISO cryogenic containers each carry up to 26,586 liters (7,023 gallons) or 12,495 kg (27,546 lbs) of LNG at -160 °C. The two 40-foot containers comply with T75 regulatory standards that call for fortified tank walls and protective structures around the tank. The containers are manufactured by Hitachi, one of several T75-compliant ISO tank makers interested in Alaska’s LNG market.
Containers will be trucked 70 miles to the Titan LNG facility near Port MacKenzie where they will be filled with Alaska LNG, before returning to the Anchorage rail yard to be loaded onto a railroad flatcar and hauled 350 miles north as part of ARRC’s northbound overnight freight train to Fair- banks. Here, the ISO containers will be transported by flatbed truck the last 4.5 miles to the Fairbanks Natural Gas storage facility. Empty ISO containers will be re-loaded onto a railroad flatcar and added to the southbound freight train headed to Anchorage. The first scheduled twice-weekly test trip will occur on 27 September. Demonstration trips will continue through October.
