Works numbers were 36320-36321 in March 1911.

For a cement-hauling industrial road, the P-P had some impressive 60-cm locomotives. Very few rigid-wheelbase locomotives would be bigger than this pair of Ten-wheelers and ride on the 60-cm gauge. The large tender was intended to carry 2 3/4 cords of wood, which the specs indicated was "fuel capacity for 20 miles". The big Radley & Hunter stack corralled the wood sparks.

Such large engines proved to have some kinks to be straightened out. A 26 December 1911 letter noted that "Ribs of engine truck centre pins interfere with the swing link crossties of engine trucks." Locobase supposes this interference had led to a derailing or two as the truck failed to displace properly when entering or exiting a curve. In addition: "There is too little clearance between the nuts of studs holding centre pin to cylr and the swing link crosstie."

On the engine's other end, "Tender end of draw bar was too long to go into pocket of tender front draw casting."

The second locomotive was lettered with the name Parnahyba.

The P-P conveyed limestone to be converted to lime in the Gato Preto kilns and thence to the Sao Paulo Railway. Acervolima's account

In addition to hauling cement, the P-P provided the service for which it was originally chartered in 1910, hauling pilgrims to the shrine at Santuario de Pirapora do Bom Jesus, which lay 30 km (19 miles) from the Sao Paulo neighborhood of Perus. Passenger service persisted on the P-P, only being discontinued in 1972.
