Steam Loco Motive

Keep the steam coming and engine running by keeping the firebox loaded.
A puzzle level with tricky actions needed in areas of restrictive viewing (see hints).
I tried to retain the overall appearance and add some play

Leisurely play, no true order of actions. Built to allow viewing as a kinetic art object.

1. There is one location that is specific for operation.

Spoiler: Hints 1

1a. It is uniquely highlighted to allow a bit of sight…

Spoiler

1b. On the right hand side…

Spoiler

1c. Below the rear most tower…

Spoiler

1d. A step creates a small square window (side view of step).

Spoiler: Hints 2

Spoiler

2a. B must stand here to travel between the tank and cab.

Spoiler

2b. The vertical slider of the tower must be up to reach the block then down to continue.

Spoiler: Hints 3

Spoiler

3a. The slider to release the front half is just in front of the cow catcher.

Spoiler

3b. It slides away from the cab until it separates and releases the front.

Pack your bags for vacation travel with this version…

Super, super, SUPER!!! I really really, really, REALLY LOVE vintage locomotives!!! Thank you very much for choosing the locomotive as your level idea! I personally thank you very much for this!!
Incredible, amazing, excellent! I always admire your talent. You always go beyond the limits of mekorama, and you do it superbly!!
A very nice locomotive. I really like both locomotives: the one that leaves for unknown distances beyond the visibility of mekorama, and the one that stands on the rails! It's very good that you made two cards. I enjoyed both a lot! Thank you.
I admire your attention to detail. I love it!! And firewood in the firebox of the locomotive, and a lantern, and pipes, and a cabin with fireman B. You even made a very similar hook to connect additional cars to the locomotive. I really like how the rails converge perfectly at the top and form a perfectly smooth railing from above. I admire all the details and their realism! Well done!!!
The gameplay is also interesting. I thought for a long time how fireman B could get out of the firewood compartment into the main driver's cab. I found your cunning passage. I like.
Thank you!
This is genius!
Of course, of course, of course 5!!!

Thank you @Denis Nazin for your valued comments.
When I first found Mekorama I was drawn to a description of it as being a “diorama” (small scene model) game with players able to create their own levels. At that same time I discovered the forum with thousands of posted level cards.
I can only imagine what detailed levels could be created if a game version was released that was double the size (from 16x16 to a 32x32 base).
Binary memory doubles at each advance (2,4,8,16,32,64,128,256…). However it might become to (time consuming) to keep interest going, especially with new players.

Wow!! Very cool & realistic design... liked the gameplay too... thanks for sharing @97 NinetySeven great job!

Superb design and very cunning gameplay. Also the added bonus of the moving version. I enjoyed this one. Thank you for sharing.

Very accurate design of a train, look very very good! Cannot guess how many hours used to make this!

Another masterpiece from you, AMAZING design!

You did a great job with the ghost metal!
I had to think carefully about how to pass this level, interesting gameplay.

Such a fabulous locomotive and the gameplay was really interesting as B checked out all the areas of his operation!

Am I the only one who can’t get B out of their area?

Thanks for trying @JustcallmeVGM. The hints (posted above) do cover the area I believe you having difficulty with…

Spoiler

The rear tower must be raised.
B must then stand on one specific spot.
(Just inside the towers area)
B will be visible through the tiny window (rotated stairs create the small window)
The tower then gets lowered
Sliding the firebox back allows B to walk into the cab area

I hope this helps you progress on through the level.

Thank you @EL797 for PCR. I try to include hints for passing trickier areas.
