In light of the Hoboken, New Jersey train crash that was staged, September 29, 2016, I have been reminded of the Volgograd Train Station bombing of December 29, 2013. Notice both attacks happened on the 29th day of the month. They also both happened on dates with '74' numerology.
12/29/2013 = 12+29+20+13 = 74
9/29/2016 = 9+29+20+16 = 74
9/29/2016 = 9+29+(2+0+1+6) = 47
You have to appreciate the details about '44' injured and '34' dead. The numbers for 'kill' and 'murder' respectively. Volgograd is also on the 44th Parallel, go figure.
Also, regarding the '29', the train station incidents were 2-years and 9-months apart.
