Infracorp Development Inc., a subsidiary of Alliance Global Group of Andrew Tan submitted an unsolicited proposal to build a people mover system which will link the Fort Bonifacio area in Taguig and the Guadalupe MRT station in Makati on October 26, 2017 to the Department of Transportation (DOTr).

[3] Following the DOTr's endorsement, the proposal is subject to review by the Investment Coordination Committee of the National Economic and Development Authority Board.

[4] After Infracorp was given "original proponent status" over the SkyTrain project, the firm began looking for an operations and maintenance partner, as well as the technology supplier.

Renderings show the trains to be nearly identical to the ones used in the Leitner-Poma Minimetro system installed in Miami International Airport’s E-Train.

Ayala reportedly plans to extend the SkyTrain to the Makati Central Business District or up to the Manila Light Rail Transit System Line 1 (LRT-1).
