Here are two pics from the electric locomotive 1009 in Assen, The Netherlands.

This was one of my favorites because of the big wheels with the spokes. 1D1.
Only 10 of these machines were built for the Dutch railways.
Voltage was 1500 Volts DC.

This was around 1972, My brother and I were standing on the platform.

1009 was towed behind 1151 direction Beilen.

The yellow train was a passenger EMU arriving at Assen Railway station.

The signal box was near the 12 sign. As teenager i quite often went after school inside the signalbox and had a chat with the signalman, and was sometimes allowed to switch the red lights on for the roadcrossing while he was pulling the lever to drop the roadbarrier arms.

Great those pre OHS days.
This is now all history. All extra track loops have been uplifted, signalbox gone and new station built with only two tracks.

The product of rotation, excitation and flux produces electricty.
