It would require Ballmer-class obfuscation to scurry around to assemble 'reasons' for the failure even to tear up a few RR tracks: the symbolic value alone, as with the Mitchell raid on Tokyo.. would have justified such a low-risk couple bombers or even fighter-bombers, with a few spares after another raid. There were So Many of those raids.

For all the Good Shows! earned in WW-II, this peculiar.. could be called -intentional- omission, in the face of much more evidence than, say, a unilateral Regime Change\ufffd invasion 'needed' 60 years later? - can be defended only by a jingoist.
(The "trade of 10K trucks for Jews", now.?. that cynical offer was fraught with obvious problems on a variety of scales. Ripe for review, perhaps - but not nearly so stark an act of omission as was the above.)
