Shot this while testing the new lens.
Didn't actually plan for railfanning, but my walk took me past the mainline, and when this MOW train approached, I just had to shoot it. Also learned the first lesson: The train comes too close quicker than you think, and if you're used to the ability of zooming way back, you're in for a surprise. But even without being able to get a wider shot, I kept it clicking, and the outcome wasn't so bad after all.
The train in question is an ultrasound track inspection DMU, consisting of two powered cab cars and an unpowered middle car. As the serial number 001 indicates, this is the first train of this type, built in 1975, retired in 1998, and reactivated in 2001. There is a second train that was built in 1996, but it had some problems and may no longer run under its own power, requiring locomotives to move it along. The interior of the cab cars consists mostly of crew compartments and washrooms, while the central car houses all the measuring equipment.
You may have noticed that the characteristic "crease" of the 110s/111s and 120s
seem to have been combined into a cross shape, giving these trains a pointy nose. They were of course based on the class 614 DMUs, which are almost identical in terms of appearance, apart from the measuring equipment and the livery.
And the 614s were based on the 624s.
