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].
