The Mayan Train: and the sleepers Mr. President?
October 17th, 2019
1. “With rain, thunders or lightning bolts, the Mayan Train will be built”
President Andrés Manuel López Obrador, declared: "Rain, shine or flash, the Mayan Train will be built, whether you want it or not." In turn, Fonatur announced that four tenders will be issued in December for a total amount of four to five billion dollars and civil works are expected to begin in April 2020. This means that the demand for sleepers is a fact.
The decision of who will supply the sleepers is an opportunity for the government to provide proof that its stated purpose of: “creating working opportunities to improve the quality of life of the (local) inhabitants. The main profitability is social welfare.

According to its analysis, the cost of construction and maintenance for one kilometer of track during the 30-year useful life is lower with wood sleeper than with concrete sleeper. From year 30 to 60 years of life of the concrete sleeper, the sleeper track costs of both materials are very similar. The wooden sleeper track has a lower initial cost because it is cheaper than the concrete one (EFE - Idom, 2013). According to the Net Present Value (NPV), sensitizing the lifespan of 30-year-old wooden sleepers and 60-year-old concrete sleepers, with a 6% discount rate, reports that the NPV difference between sleepers of wood and sleepers
