An accurate attack on a bridge comes from the side, not straight down, and is aimed at destroying the support structure of the bridge. As the USAF found out in Vietnam, you can hit the rails on the bridge (or any part of the bridge decking) and make a nice big hole. That will shut down traffic much longer than blowing up a rail line on land does. However, depending exactly on what was hit, it usually can be fixed in a few days. Not great, but not terrible. However, if you destroy one or more support structures, fixing the bridge becomes a major engineering task.(04-25-2022, 11:27 AM)TrumpCard Wrote: Russia is for sure going after rail supply lines in the Donbas:
I don’t see info on whether Russia is trying, or succeeding, in knocking out rail lines deeper in Ukrainian controlled territory.
Russia might be hitting things but doesn't seem to be knocking out rail lines for long.
It has been suggested that even Russia's "precision" ordinance can't make a side strike on a bridge abutment (a large fixed target). That may be true, because I simply don't believe the Russian military is that stupid. They know what the target should be. Possibly they also know they can't hit it?
UPDATE: https://www.yahoo.com/news/odesa-militar...51161.html
Three missiles. Two missed the bridge entirely. One hit the on the bridge deck (apparently). Damage minimal. Railway line is being repaired. Yep, they appear to be unable to hit things reliably.
Substation OTOH are a good target. Either they aren't hitting them accurately or Ukraine is doing a work-around. If the transformers are OK and only wiring was damaged, it can be fixed pretty quick. Most electrified railroads of any size have a "portable" substation mounted on a semi-trailer that they can move to temporarily replace a substation while they work on it. They seldom have more than one such unit. It is also possible under some circumstances to power a "dead" section of tracks from an adjacent block. This is tricky and usually involves significant speed restrictions. This is something you normally don't do unless you have tried it and know the issues. You can easily blow up another substation if things get out of control. A well executed attack on the substations will shut down the line, so let's hope the Russians can't pull it off.
