A streamlined switcher - that's the 30s for you.

Not really. The driver's cab is square. But it has some streamline like rounded corners.

Second loco looks like one of the Dutch locomotives we sold them  that used to operate on the Woodhead line.

Yes, they are both Dutch, sorry I really should get in the habit of adding descriptions to what I post.

Interestingly the catenary also looks identical to the 1500V system we fitted on woodhead. I guess we played a large role in Dutch electrification postwar.

The dutch just like southern france use both 1500 kV. see this handy map off of wikipedia:

 

586px-Europe_rail_electrification.png

750 V DC voltage (orange)
1.5 kV DC voltage(pink)
3 kV DC voltage (yellow)
15 kV, 16.7 Hz AC voltage (slate-blue-gray)
25 kV, 50 Hz AC voltage (green)
 
 
I guess the Dublin area is metro rail?

Yeah, the French Network was ALL 1500V (where it was electrified anyway), till they nicked/liberated the 25AC system postwar from a line where it was under test in Germany. Or at least, so ive read.

 

Yeah probably. Looks like it includes Merseyrail and the Newcastle metro system as well.

 

Not sure why they dont include scotland? There are significant lines there that are 25AC, as well as the Glasgow underground system which would be I guess 1500v.

Considering that much ofnthe english rail network is still not electrified, the maker of the map should have included Scotland as well. The mapmaker probabaly did not have all information. But as a general overview of europe and its different electrification it seems good enough. hence locos like the bombardier EUrotraxx and the siemens Eurosprinter have been developed, that can drive verywhere in europe as long as the rail gauge fits.

 

 

small local railways have all manner of differrent electrification, but it makes not too much sense to list all the small mining rails, subways, citiy rails etc., because they are isolated. Berlin e.g. uses one DC and one AC system in its metro, because those used to be two different rail companies that were later fusioned to the current operator. The tram lines in Berlin use a third system.

I took this screen shot from a vid on facebook. Translation said "Fast Rail Belgrade-Budapest, test drive"

A few remarks.

Not all of France was electrified with 1,500 Volt DC, they had a mix because the electrification had been done before the nationalisation.

The Dutch locomotive looks rather German.

Germany didn't test 25 AC. We had committed to 16 1/3 shortly after 1900. 25 AC wasn't viable until after the war.

The steam loco is a german type. The cars being pulled look like an old Bundesbahn pattern paint job. But that electric locomotive looks not very german to me.

Correct, I didn't notice the electric one. The looker gets pushed.

Nitpicking me could not let that defacing of the most weird power frequency without an answer: 16.67Hz.

In Spain we had mainline voltages of 1.5kV DC, and 3kV DC. The HS lines were electrified at 25kV AC. Then there are the metros, with a curious mix of voltages, from 600V DC in Metro Madrid to the -1.2kV DC, 1.2kV DC, and 1.5kV DC used in Metro Barcelona. Metro Bilbao uses 1,650kV DC, and some parts of Metro Valencia use 25kV.

Correct again. 16.67Hz or 16 and 2/3 was the closest one could get to 50 Herz electric motors at the time.

As my instructor on electric traction systems, with that frequency one still could use high voltage in the catenary and a transformer with taps to vary the voltage across the electric motor, which was of the universal type, i.e., a series-excited DC motor that could also work in AC. High power universal motors have problems with high line frequencies, so the reduction to 16.67Hz.

I take it that is why the locomotives are changed at the German-Dutch borders?

Scotland is coloured green as far as the Antonine Wall or thereabouts, which is fairly accurate. Electrification is limited to parts of the central belt and East and West Coast Main Lines south of Glasgow and Edinburgh. They've accidentally left the Western and Northern Isles coloured green too.

Glasgow Subway is 600V DC, converted from cable hauled.

It could be because of incompatible signalling systems, also, but it is not rare that railway personnel's union demands also had something to do with that.

I think there is an ICE-3 sub series of EMUs able to run in the Netherlands, Belgium, and France.
