foundation design - need quick answer
(OP)
This question is probably answerable by someone familar with bridge design, but the AREMA design manual for train structures indicates that impact loads are not normally considered for foundation design. Does that include reinforcement or are they just referring to stability issues (such as bearing pressure and overturning)?

"bearing pressure and overturning" = foundation sizing
That's the distinction I'd make- don't know anything about the standard in question, though.

Note though that AREMA does indicate that you DO have to consider vibratory effects in your footing design. Depending on you structure this could be more a more serious consideration than an increase of the live load by a certain percentage.
