# F40PH
F40PH is 4chan's answer to Furry Friday: anons dump photos of an Amtrak diesel-electric locomotive to drown out furry porn threads on the /b/ board. The custom began in December 2006 and was formalized by February 2007 when an anonymous poster calling himself Vipper declared Fridays the day for F40PH train images. By August 2007, Urban Dictionary had logged F40PH Friday as the replacement tradition.
## Origin
Train-posting on /b/ as a response to Furry Friday goes back to at least December 2006, when the earliest archived instances appeared on 4chan[2]. Furry Fridays had been a /b/ ritual since 2005, with anons posting furry porn in bulk every Friday. Many /b/ regulars felt furry content did not belong on an anime-focused random board, so they answered each Furry Friday thread by drowning it in photos of the Amtrak locomotive[1].
In February 2007, an anonymous poster calling himself Vipper formalized the counter-tradition, declaring Fridays as the day to post F40PH images instead of furry art[5]. By August of that year, a definition appeared on Urban Dictionary stating that F40PH Friday had taken over from Furry Friday[6].

## Overview
A typical F40PH thread opens with the battlecry 'YIFFIN HELL, FURFAGS' and a flood of locomotive photos loaded in bulk via directory dumper software[1]. The subject of all those photos is the F40PH, a real EMD diesel-electric unit used by Amtrak since 1976, with a 3,000-horsepower 16-cylinder prime mover and a top speed of 103 mph[6].
F40PH posters give the locomotive mock reverence, placing its scale alongside Chuck Norris and Billy Mays comparisons[3]. Urban Dictionary contributors describe it as 'the best locomotive Amtrak ever operated besides the AEM-7'[6]. Among hardcore railfans known as 'foamers,' the newer General Electric P42 'Genesis' is viewed as the 'anti-F40PH'[3].
## How to Use
Participation typically means dumping a directory of F40PH photos into a Furry Friday thread, usually opening with the shout 'YIFFIN HELL, FURFAGS'[1]. Images are often ordinary train-spotter shots of the EMD unit; the comedy is in volume and context, not captioning[3]. Reception depends on the host board: /b/ anons take it as sport, while Fchan hands out immediate bans for any F40PH content[12].
