1/ #Trains #Trainspotting #TrainThursday #Railways - Who likes trains? I always have... Here are some from Chattanooga, Tennessee at the Tennessee Valley Railroad and Museum! #TN225
2/ #Trains #1940s #1950s #forests - Admission gets you on to a 40 min. train ride through the forest, Missionary Ridge Tunnel and bridges in a vintage train... Each compartment is different, but all are from the 1940s to 1960s or so IIRC.
3/ #STEM - @tvrail's turntable operation at the second station at the "end" of the ride is great. It takes ~15 minutes. Then we all re-board for the 20 min. ride back to the first station. Nicely done and worth the $22/person tickets!
@tvrail 4/ #Chattanooga - Tennessee Valley #Railroad and #Museum - more photos near the turntable and inside the train and bridge pylons from one of the former bridges. @dembumpaku @mizurin1970 @americanrails @dennisondepot @railfandepot @gw_driver @DonkouPod
@tvrail @dembumpaku @mizurin1970 @americanrails @DennisonDepot @RailfanDepot @DonkouPod 5/ #Trains #STEM #trainspotting #railways - Tennessee Valley #Railroad and #Museum - more photos of the static display by the parking lot. I saw the train depot used in the splendid movie about Jackie Robinson, 42, starring #ChadwickBoseman.
@tvrail @dembumpaku @mizurin1970 @americanrails @DennisonDepot @RailfanDepot @DonkouPod 6/ #Trains #travel - Tennessee Valley Railroad and Museum - more photos of the static display by the parking lot. The next post will probably be the last on the subject, but it's a beast!
@tvrail @dembumpaku @mizurin1970 @americanrails @DennisonDepot @RailfanDepot @DonkouPod 7/ #Trains #travel - Tennessee Valley Railroad and Museum - Canadian National Railway 5288 J-7-b class 4-6-2 Pacific coal/steam engine was built in Montreal in 1918!!! It weighs 268,000 pounds (134 tons)!

#PoliceReform #TyreNichols #Tyre #Video #Riots - Bodycam footage pf Tyre Nichols' murder by 5 police officers is due for release tonight. Police across USA are bracing for riots and violence. But violence will only harm and destroy communities with NO benefit. Please don't do it.
#RodneyKing #TyreNichols + Memphis, HELL NO trend. 1992's Los Angeles Rodney King riots did great harm. This was both the immediate damage and massive subsequent economic devastation as companies and customers stayed away. What do #riots do to the communities they devastate?
3/ #PoliceBrutality #TyreNichols: People have every right to be angry. I'm angry. 😠😠😠But for once, the system actually seems to be working. The five #Memphis #police officers have been fired and arrested. Quickly.

#FirepowerFriday #WW2 #ships: #Germany's mighty and handsome 52,600-ton 8x15" battleship Tirpitz at speed↖️ and Tromso fjord, #Norway↗️. ↙️↘️Perhaps on November 12, 1944 when she was sunk by RAF Lancasters. Her clean lines betray a lack of AA. Photo: ACME.
2/ Per reddit.com/r/WarshipPorn/…, here's a #USNavy manual excerpt on Tirpitz identifying what is what.
3/ Tirpitz was, of course, the second and last ship of the Bismarck-class battleships. These diagrams from forum.worldofwarships.com/topic/199855-t…, etc., show her gentle evolution over time, especially ↖️↗️↙️where we see improvements in AA, radars and camo. ↘️ is similar to ↗️.

T-34 #military #history – The apex of Soviet Christie suspension #tanks is the 33 mph T-34/85 with the L/55 D-5T 85mm main gun. Note: the larger vehicles (T-34/76, T-34/85, British A-27 and A-34) had five wheels a side).
#military #history – The most-famous Christie suspension vehicle is the Soviet T-34/76. It lacked the hybrid solid rubber tire road wheel/track configuration but just superb wide traction tracks helping it sprint over terrain its opponents couldn’t handle.
3/ #TankTuesday I'll post four T-34 interior shots in a moment as a reply to this later model T-34/85 with the larger gun, larger turret, and five-man crew instead of the original T-34/76’s four-man crew.

#RussiaUkraineWar #Challenger2 #UkraineArmy Challenger 2 tank: 447 built 1998-2002. World's best tank? L/55 120mm barrel. Crew: 4. Armor: 2nd gen. Chobham. 63 long tons! 1,200 bhp; V12 diesel; 37 mph. Ukraine to get 14. Great video from @PhilLoder. 1/
@PhilLoder 2/ Challenger 2 has digital fire control computer, laser rangefinder, 8 periscopes and 2 x 7.62mm machine guns. How would it fare vs. #RussianArmy's T-72B3, T-90 / T-90M or T-14 Armata? @Burntime0101's great photos show Megatron emitting a smoke screen!
@PhilLoder @Burntime0101 3/ Challenger 2 is based on the similar looking Challenger 1 but shares only 3% of the parts! At the gun’s root is the big boxy Thermal Observation and Gunnery Sight II (TOGS II) for night vision. It relays to the gunner's and commander's monitors and sights. ImageImageImageImage

#USNavy #USAF #avgeeks #aviationlovers - NATF-22? Yes, there could have been a navalized F-22 stealth a la F-14 Tomcat with swing wings, Mach 2.25 supercruise, heavier landing gear, and so much more. So why did the US Navy opt for the F-18 and F-35 instead? I'll tell you... 1/ Image
2/ Congress wanted the NATF-22 but the US Navy pushed back. The swing wings would have compromised stealth and added to the maintenance woes. As it was, the F-14 was already far too expensive especially in the absence of the #USSR's military, which is why the F-14 was retired. Image
3/ The naval F-22, aka Sea Raptor, would have been slower than the F-14 and cost more. The F-22's unit cost was, ballpark, $138 million. A navalized one surely would have cost at least 20% more based on F-14 vs F-15 costs. en.wikipedia.org/wiki/Lockheed_… Image

#Hurricane #USNavy #OTD: December 18, 1944, Admiral Halsey catastrophically orders the US Navy’s vaunted TF38 into #TyphoonCobra. TF38 has seven fleet carriers, eight battleships, ~60 light carriers, cruisers, and destroyers. In all, USA loses three... 1/
2/ destroyers on Dec. 18 killing 790 sailors. USS Iowa @ussiowa, CL Miami, etc., damaged. Light carriers Langley and Cowpens (above tweet) roll through 70 degrees, sending airplanes overboard or into each other, starting big fires. 146 aircraft lost!!!
3/ In contrast, USA lost 123 aircraft in June 1944 Battle of the Philippine Sea. Destroyers Hull↖️, Monaghan ↗️ and Spence ↙️ sink. Maddox ↘️ and others are pounded but survive. 30 US Navy warships sunk or damaged total! #disasters #WW2 #Pacific #Weather
