Another in my series of bombs on railways. (see the tags for Railway IEDs in the RH column) This one an unsolved case from 1880 where the perpetrators of an attempt to blow up the London and North Western railway were never discovered. Early on the morning of Monday 13th September 1880, a gang of workmen were doing a routine check of the line between Bushey and Watford, about 16 miles north of Euston. They were half a mile from Bushey station when they discovered an explosive device, apparently damaged by a passing train. The device consisted of a package of dynamite placed beneath the rails. Connected to it was a rubber tube filled with gunpowder and some detonators. The assessment is that the rubber tube was somehow placed on the line, with the intent that a trains wheels would have crushed the detonators, ignited the gunpowder and hence initiated the dynamite. The workers recovered the package and took it to the police, suggesting that the rubber tube had fallen off the rail due to the vibrations of the approaching train. A separate, slightly contradictory, report suggests the tube was cut by the trains wheels but no detonator had been crushed. I suspect the former is more likely. The dynamite was in the form of cylinders, 4 inches long, and one inch in diameter, then wrapped in newspaper, and then brown paper, tied with whipcord. Later analysis suggests the dynamite and detonators were standard commercially available materials for quarrying.
The motive for the attack was unclear. One suggestion was that the device was the work of Russian “nihilists” attempting to assassinate Grand Duke Constantine of Russia, who travelled on the line a day or two earlier.

A brief update. I note from the annual report of the Chief Inspector of Explosives for this year, by Lt Col Majendie – he mentions this incident in passing but states that his presence and advice in investigating the incident was not requested.
