International Railroad Discussion > Douro Valley Train in Portugal

There is a rail passenger service in Portugal that runs from Porto up the beautiful Douro River Valley.

Most service is provided by DMUs and a few runs are handled by locomotive pulled trains of rebuilt Swiss cars from the 1940s.

Which runs are currently handled by locomotive pulled trains?  The information I have (8:30am and 1:30pm from Porto) is probably out of date.

I also read that there are plans to electrify part of the line and wonder how that is coming along.

Many thanks,
