The Mexican government has selected the Transconsult Egis consortium (Egis, Transconsult, and Triada) for the supervision contract of the Tramo 4- fourth section of the Maya train PPP project. The 250km-long tramo 4 has 3 railway stations, with the first located in Chichén Itzá, the second in Valladolid, and the third in Cancun. The route of the 180 D road (between Kantunil and Cancun) will be used for the construction of 225 km, with only the ends of the line diverging from it (21km in one direction and 7km in the other).

Transconsult Egis has been commissioned to supervise the construction of the railway track bed and track, and for the adaptation works on the road running parallel to the alignment. The contract also includes works supervision for the maintenance centre located close to Valladolid and various structures.
