Something new coming to High Iron: Rerailed is electric trains! Here are our first samples - a Nippon Sharyo McI electric multiple unit car painted in as-delivered 1982 South Shore Line livery, and a Kinki Sharyo P3010 light rail car painted in the current Los Angeles Metro Rail livery.

Line your switches for High Iron: Rerailed! After a small break, we're back to work! We've remade the GP40 and knuckle coupler models for High Iron, to be used in our upcoming Rerailed project! Much work is going to be poured into development going forward, revamping everything across the board!

Sorry for our absence here on Bluesky! We announced on other platforms that we're in the midst of remaking #HighIronRBLX from the ground up. Take a look at the following images and the linked thread from @flusterco.nekoweb.org for our progress! #Roblox #RobloxDev

Apologies for the silence, we're just now getting back in the saddle. Here is some new content coming to #HighIronRBLX! We have a pair of ATSF GP30s and two rebuilt ATSF GP30u's, modeled by @flusterco.nekoweb.org, as well as a small speeder made by @forgednostics.bsky.social! #Roblox #RobloxDev

Here is some new content coming to #HighIronRBLX! We'll be adding the GE 60-ton boxcab as well as working train order forks, which can be manually armed and automatically interact with any passing trains. All cabooses and observation cars now have custom player animations as well! #Roblox #RobloxDev

These are a pair of boxcars based on the Pullman-Standard 50 footers built for the Southern Railway. One of them is my first to feature graffiti, representing a recognizable piece from the mid-2010s. #Roblox #RobloxDev #HighIronRBLX

Here are all three caboose animations I did for #HighIronRBLX. I'm really happy with the results even if they're fairly basic, as this was only my second experience with animating in Blender! #Roblox #RobloxDev

In addition to gated crossings, we'll also be adding custom seat animations to the tails of cabooses and potentially other rolling stock, such as freight cars. We hope you'll find some creative uses for them! #Roblox #RobloxDev #HighIronRBLX

Take a look at our first gated crossing! You'll find this one at the upcoming town of Sunray, which will be the third largest town in Red Rock once the map is fully complete. We tried to make the crossing sequence as realistic as possible! #Roblox #RobloxDev #HighIronRBLX

The drive system has been rewritten! It features an all-new interface, notched throttle for diesel locomotives, support for all lighting options, more cameras, and wheel squealing when moving through curves. Coming to #HighIronRBLX in our second update! #Roblox #RobloxDev

2024 was a wild year for me, and as such I kind of took a break from my usual creative outlets. However, I got back to work at the end of it to get out just one last thing - an EMD GP30 for High Iron, by @nebulagamesrblx.bsky.social ! This is my best model yet, and I hope to make more like it!

We're coming up on the end of 2024 and it's apparent that High Iron's second update will not be releasing this year. Progress has been slow due to numerous factors, and at this point, it can be assumed that we are taking a break for the holidays. We'll be back soon! #Roblox #RobloxDev #HighIronRBLX
