Upgrading the last pallet bridge
With all the wet weather it recently occurred to me I still haven't replaced the last pallet bridge, and when clearing the drain I noticed a wee cave in and debris building up with a few branches mixed in with the clay. So the decision has been made to remove the pallet bridge and replace it with my 2 remaining railway sleepers.

7.25" Point signals
A quick post showing off the points, simple to install and can be removed and stored inside when not in use. It uses micro switches attached to a rod that connects to the points/turnout. The lights seem simple enough to replicate for the other turnouts, a good winter project for rainy days.
With regards the block signals, an Idea was to use security PIR sensors set above various positions wired back to a hub to control the signal outputs.

New Locomotives & Wagons
Finally a post again, I've been working on the bottom horseshoe loop trying to get it level but still weeks away from finishing it. In the mean time I've been acquiring a few new additions to the railway thanks to Dave in Waihi. Firstly is the locomotive training simulator in the form of a rocking locomotive for kids. The idea would be for the trainee to sit in position with a VR headset and an operator will roll him/her backwards to give the impression of movement and forwards when braking.

Artificial Grass
This week I've been laying some artificial grass on the outdoor 1:24 gauge railway as an attempt to control the weeds and grass from overtaking everything. I also happened to have lots of old concrete bags laying around so I covered the embankment with em, pinning them in with 8" staples. For the grass mats which were 3x1metres in dimension I split them down the middle and stapled the mat into the wood base and on the ground pinned them into the ground with the 8" staples. The ground is covered with leftover plastic from the pond and soon to be covered with gravel.

Happy New Year
Happy New Year
Much like 2020, 2025 starts off in my calendar as W. T . F! hopefully this year being exactly a quarter of a century should count for something in the luck department.
Much of my time has been divided between work and concreting with the occasional arch bridge thrown in for good measure. A concrete lip has been added to both sides of the roadbed ready for a layer of brick to bring it up to height.

Silver Fern
Things have been rather busy in the last month, I ended up getting my hands on a 7.25" gauge silver fern that appeared on trademe. The fern has always been special to me, dad took us kids on a trip in her to rotorua in the early 90's and everything about it felt modern, right down the air operated internal doors.
So to celebrate I decided it would be a neat idea to 3d print it in 1:24 scale, the 3d printing part is almost finished with the underside still in progress. I intend on 3d printing the seats this time around, this version is more of a test print as I've altered the front end and with a bit of effort managed to thin out the walls.
