I am an earthquake researcher in San Francisco, California and seek your help in finding technical data about a Japan electric locomotive.
The link below shows a photo of a JR East Loco that was toppled during earthquake in 2007. I am studying the ground shaking intensity that would cause it to tip over. I think it is a Series 115 loco.

I need to know:
1. Loco weight
2. Loco dimensions (length, width, height)
3. Loco drawing of front and side views
Please advise on where I can obtain this information
Thanks
Here is what I found on the German Wikipedia website: https://de.wikipedia.org/wiki/JNR-Klasse_115
According the photos it seems to be a 115: https://2.bp.blogspot.com/-F53EMarT7_A/UfR_GRq8JUI/AAAAAAAAFOM/El9lhP8EQzc/s1600/115Nagano640.jpg
The Series 115 is an electric multi unit (EMU) design. It doesn't have locomotives but a number of cars is propelled.
Dimension per car: Length 65'- 7.4''; width 9'- 8.4''; height 13'- 4.5''; gauge 3'- 6''; weight 32.85 tons.
Here is a 1/80 model side view: http://www.1999.co.jp/itbig17/10179365a2.jpg
And the closest to a drawing I was able to find: http://www.1999.co.jp/itbig17/10179365t.jpg
Disclaimer: I'm not sure how correct the above information is.Regards, Volker
I believe Volker's information is correct. Here is the picture from the linked page:
Part of the 'secret' here is likely to be the 3'6" gauge and relatively wide carbody; it would help to know the proportion of P- vs S-wave motion effective at the railhead, but note that the visible trailing car of the set remained railed. A significant piece of information to know would be whether the flange gauge corner remains close to the railhead (i.e. tipover) or if the 'low' wheels are displaced outside the line of the rail, indicating some lateral motion or displacement (I can't tell from the picture, but someone more familiar with the 115 class, perhaps tomikawa tt, would know).
Volker:
I appreciate you quickly finding this informations for me.
I have another case I want your help with. This time it is a loco in New Zealand. I will post it as a separate request.
Thank-you very much

Thank-you for confirming that loco is Series 115.
The earthquake motions causing tipping are the surface waves since these cause the most violent shaking.
I have another case that I would like your attention (New Zealand loco). I will post this as a new request.
