13/Polish Self Propelled Tanks. By outbreak of WW2 armoured train innovation had continued with self propelled rail trolleys powered by tank tracks, these became a staple of Polish armoured train consists for patrolling and fire support.

8/Containers. Container handlers need wide turning circles and hard standing. Rough terrain container handlers are large but can work on unprepared flat ground and need HET moves to get to site. Trucks need to be ready to recieve containers, ground dumping is waste.

1/ The Parrot Wagon. Copied from an existing LNWR design in 1917, this was the worlds first tank carrying wagon. Designed to carry 40t and fitted with screw jacks to prevent dynamic loading of the bogies whilst loading/unloading tanks. These jacks would appear on all tank wagons.

14/Conclusion. To use rail effectively, planners must be aware of gauge constraints. Embarking units must be efficient in loading drills and carry out the right prep. Military railway engineers can assist in gauge clearing routes and rectify obstructions.

Damage to Ukraine’s railway bridges amounts to over 10% of their total war damage. To help rebuild them, we’re providing crucial equipment and engineering expertise, including… ✅ Bridge repair and tunnel lining equipment ✅ Training for Ukrainian engineers #StandWithUkraine

7/Palletised stock. Used for CSUPs, Ammo and other pallet stock. Needs a small turning circle on flat and well drained ground. Enhance with hard standing. Use forks to unload, increase numbers for quicker discharge straight to trucks. Ground dumping pallets is waste.

The military railway bridging 🧵 Road bridge capability is well supported in NATO with MGB & LSB systems. Railway bridges with higher dynamic loads have less options, planners for future warfighting need to consider what bridging options are available to secure the rail LofC.

25. Train 1 ran in December 22 from Barking to Poland with transhipment straight to UZ. Train 2 ran once the Lydney training bridge was repacked in February 23 with a similar handover in Poland. UZ moved stock forward into country and dispersed ready for use.

2/The RECTANK wagon. Purpose built to WD spec in 1918 with a capacity of 38t. It had a slight well and fitted with screw jacks to reduce dynamic loading on bogies when unloading tanks. Would serve in WW1, WW2 with some leaving service in the early 1990s.
