Operating mechanism for the Michigan Avenue bascule bridge in Chicago [OC]
The bridge still operates a number of times a year. The mechanism is driven by a DC electric motor, by memory about 100 hp.

One of the machines that caught my eye at Meyer Made during my visit, it has B axis milling head and twin cutting capability, the M1 head and turret works on both sides of rotor components simultaneously, and it helps cut cycle time, along with that it also reduces chatter during intermittent cuts

Just one of my old blueprints, with a few minor corrections. I hope you like it; any suggestions are welcome

I built this as a side project for work, because we got lucky and caught a failing air brake component because someone was under it and saw it shift - So I made this so we can do a better job inspecting the brakes.

Seen this loader at Brownsville, wondering what it is. Serial tag says it’s a terex 72-81aa, body is a Michigan.

This is Southern Pacific Steam Locomotive 745. I have had the privilege of being part of her preservation for more than 40 years. From the day she was removed from her long-static display, to the first time she breathed steam again, and now through her current re-tubing and other work as part of her 1,472-day inspection, I have been fortunate to witness every chapter of her remarkable journey.
This project has been far more than the restoration of a locomotive. It has been a lifelong source of purpose, perseverance, and learning. Every challenge we faced along the way became an opportunity to grow, and every milestone reminded us why preserving history matters.
My hope is that 745 continues to inspire generations to come. If you're a railfan, or if you have children who are fascinated by these incredible machines, encourage that curiosity and keep the passion alive. The future of our railroad heritage depends on those willing to appreciate, preserve, and carry these stories forward.

Visited Bonastre and was impressed by one of their older machines. It's producing high volume medical and dental components with features like a trapezoidal thread with just 0.3 mm tolerance, special knurling, and diameters held to ±0.01 mm,while delivering a part every 5 seconds. Truly fascinating

Spotted the Wightlink hovercraft arriving at Southsea Beach in Portsmouth, UK.
It still amazes me that you can catch a scheduled hovercratt as part of the UK's public transport network.
The crossing to Ryde on the Isle of Wight takes around 10 minutes, making it the world's only year-round commercial passenger hovercraft service.
Watching it come ashore is almost as entertaining as riding it!
Has anyone here travelled on it? What other unique forms of public transport do you think deserve more attention?

Taken during a weekend tour of the production plant. Got to see all stations, from raw material, mash production, bottling/canning, etc.
