Sometimes on a Monday you get a loco swap at Regua on one of the return workings, as they like to swap out the thunderbird loco stationed there on occasions. Had it happen last year on the 868 train. Earlier they’d also had a loco waiting at Pocinho to drop on the back, so I got three different 1400s on one return trip. I think the previous year’s visit they just ran round at Pocinho and I got the same haulage back.
