On the 402 kilometer long 75 cm gauge line of the "Trochita" (former Ferrocarilles Argentinos) from Ingeniero Jacobacci to Esquel, there is only one, about 100 meter long, tunnel, when the line leaves Cerro Mesa, after the crossing of the Rio Chico. 2-8-2 Baldwin built # 1 and # 16 are leaving this tunnel with a Trains Unlimted Tours (TUT) charter, which travelled the entire line during 3 days in 2007.
