Here in Portugal, four from the five daily services between Porto and Pocinho, along the Douro valley are booked for class 1400s, as mentioned. Only the 1525 ex-Porto and last one back off Pocinho in the evening are units, with even this turn meant to go over to 1400s soon. There are currently five 1400s for the three diagrams, 1408, 1424, 1436, 1438, 1455, but the full pool is meant to be eight locos for five diagrams. 1408 is temporarily in the pool in place of 1415, whilst 1413 is also on emergency train duty and will return to Porto sometime soon. 1429 & 1461 are both under overhaul at Barreiro and will join the Porto fleet - 1461 is almost ready, 1429 might be June/July.
As an aside, the class French styled 2600/2620 electrics are due to start work on Porto to Valença Inter-Regional trains next month. Initially, just a couple of diagrams, but eventually they will cover all services, using ex-RENFE Arco coaches. Both of these lines will make Porto a rather nice hub for loco hauled workings, diesel and electric.
