it seems to serve similar functions to a caboose. (Braking power/maintain coupler tension, crew rest, mobile office, shove platform/monitor train in motion, sometimes a bit of cargo?)
In the past I have idly wondered why US cabooses seem to be so big, this explains it I think. Probably due to the much greater distances that those huge US freight trains travel, most of your list seems a bit OTT to me! Particularly the "crew rest" and "mobile office" - for that read "a stove to make a brew and shelf to put his paperwork on".
Yes they did sometimes carry a bit of cargo, but those vans were usually described as "Road vans" AFAIK.
I appreciate the insight as to the scope (or limit thereof) of a brake van's amenities. I grew up visiting and playing in cabooses (though they were already mostly obsolete by that time) but only ever saw a brake van on Thomas and Friends, and I only remember one shot of the inside of one. Lonsdaler, regarding the high viewing point, starting in the 20s and 30s a lot of cabooses were made with bay windows instead of raised cupolas, echoing the guards' duckets seen on British stock. (Extended-height freight cars were getting too tall to see over, and crewmen could be thrown from the cupola seats and injured due to coupler slack.)
I had been hoping to sneak a bridge into a low spot on the NVT to take a photo for the quarterly contest, but I think we might need a really big bridge to get over all this snow!

There's a railway in there somewhere. After a week it's melted enough to see the top of the station and water tank, but that's about it!
So while I wait for the big melt I've been working on a tough little critter for the kids. The little diesel 'Moke' used a hood and cab as pieces from a full kit, and the shell has never quite fit right over the relatively large salvaged motor and gearbox. I decided it was time for a twin that followed the full design as a unit. (Rod, I think I spotted one of these on your railway as well?)

Never content to leave a kit unmodified, I designed a simple two-wheel-drive chassis around an N20 motor with dual shaft gearbox, which should hold up better to kid hands than my hodgepodge belt system. The standard size should allow swapping the drive unit if I end up wanting to use a different voltage or gear ratio. There's probably just enough room in there for a belt or chain to convert it to 4WD eventually.

Since taking this picture I have switched to larger 20mm (less flanges) wheels, added traction tires to the drive wheels, and reversed the chassis to put the drive wheels under the hood (where the weights are). All it needs now is a battery that fits under the hood, and a switch to make it go. In testing with a 2S battery it is slower than Moke but can pull a bit harder thanks to the weights and tires.
