Abandoned CPEF n1

This is the CPEF(Companhia Paulista de Estradas de Ferro) nº1 I don't know to much about this locomotive and not founded to much in the internet, it is one 4-4-0, the year of inauguration of the first stretch of the railway was 1868, I belive this locomotives was built maybe one year before, this locomotive should be in a museum but I don't know why this is abandoned, the locomotive is in the abandoned maintanance shed of the CP in the city of Jundiai, state of São Paulo, Brazil.
