finally, a photo of the Oct 1895 Granville-Paris Express wreck from the other side of the train

above is the view we are used to seeing

here are a couple of photos I haven't seen before, thanks Steve!

and here they are rigging a way to lower it without destroying it

There's the Great Minturn, Colorado Copycat Crash of 1913. At least it was just the Denver and Rio Grande Railway Co. roundhouse: (thanks Steve!)

Velodrome d'Hiver, Paris, 1911

imagine what it would be like to be so excited to watch motorcycles race, for the first time ever, on an indoor board track, at the beginning of the motor age.

But this isn't a bunch of motorcycles for racing,  as NZ Carnerd pointed out:
They are cycle pacing machines. Note the style of the handlebars which keep the rider upright so he can provide a 'windshield' for the following cyclist.

The Velodrome d'Hiver (literally Winter Velodrome) and 'motor-paced racing' both have wiki pages.

Note the bikes have 'buckets' under the engines so that they don't drop oil on the wooden track, and the bikes have flat belt drive. A Google image search for 'pacing motorcycle' yields many interesting pictures but none I saw had the 'buckets' under the engines like those here.

Chabot sur Automobilette pris en 1913 lors de la course Paris-Tours

I don't think I've ever seen a vehicle with a passenger sitting in front of, and blocking the view of, the driver
