The offer submitted by Talgo is worth about 1.22 billion levs for trains with a minimum of 383 seats and a 36-month warranty, the ministry of transport said in tender documents published on the public procurement register's website on Friday.
Rival CRCC Qingdao tabled a bid of 607.2 million levs for the supply of trains with 406 seats in total and a 60-month warranty period.
The tender was launched by the transport ministry in September, as part of 2.72 billion levs worth of public procurement procedures to upgrade the country's rolling stock.
A separate tender for the supply of 35 single-deck electric trains was suspended in October due to a complaint by Czech engineering group Skoda Transportation.
