The use of this route is marginally more expensive than the Vientiane direct to Laem Chabang route, from 2,503 USD/TEU to 2,518.5 USD/TEU. The confidence index is slightly lower at 3. This is because rail transport is not considered as reliable as road transport between Lad Krabang and Laem Chabang. This intermodal link is promoted by the State Railway of Thailand to ease road congestion to Laem Chabang port but presently the service is not reliable enough, and has diverted a lot of cargo to go by road between Lad Krabang and Laem Chabang[6].
