Los datos han sido adaptados para uso escolar clasificándolos en los siguientes rangos: ferrocarriles de varias vías o multivías, ferrocarriles de una sola vía, ferrocarriles ligeros más los que discurren por el terriorios urbano producto del descimiento difuso de las ciudades, líneas de ferrocarril en mal estado y líneas sin datos.
En los metadatos del mapa de la WFP se ofrece la siguiente información: "This layer contains the railway network. This dataset brings together various sources such as OpenStreetMap, American Digital Cartography, Global Discovery, VAM data from different COs etc. It is updated regularly with inputs from WFP logistics but also from many partners through the Logistics Cluster and the Logistics Capacity Assessment (LCA: dlca.logcluster.org). The information is compiled at a global level by the Emergency and Preparedness Geospatial Information Unit at the World Food Programme (WFP) Headquarters in Rome, Italy. This dataset is at a global scale and is updated country by country... Additional information regarding the different fields of the layer. The "source" field can refer either to the source of the geometry or the source of the main attributes. Several sources can be accepted for the same feature (list of names) The "remarks" field can be used to enter necessary information for the specific segment of railway, which can not be stored in other fields (e.g. has been closed the last 10 years, single track etc.) The "updatedate" timestamp without time zone: This field holds the date of the last update. It is calculated automatically at the database level while submitting the edits. It is different of the lastcheckdate because the user can neglect to specify the date manually or because sometimes it is necessary to apply minor changes (e.g. change the status or correct misspelling) without checking all attributes".
