So many questions! So little time!
- How does the train not drift without guides to keep it on its tracks?
- Where are its tracks?
- Where and how does the train generate power to so much as even move?
- Where are the engine throttle and break lever, etc.?
- How does the train make turns with such apparently stiff connections?
- How are the rooms possibly lit when all of them lack lights and all but the locomotive lacks windows?
- Where is the pull chord to toot the train's whistle?
- Where is the train's whistle? Does it use a bell? A horn? Does the train have any kind of auditory method of alerting those around it?
- How can anyone tell the train is about to hit them at night when it's silent (due to lack of clickity-clack and horns/bells/whistles/etc.) and completely dim?
- How do trains in front of, behind, or in any position relative to the train see it so that a collision can be averted when every car lacks lights?
- Do you really trust every single individual that boards the train enough to allow them to enter through the locomotive with no barrier separating them from the engineer and train's controls?
And so on. Of course, that wasn't exactly "So little time!" if you took the time to read all of those questions, so...
tl;dr (the "So little time!" version): There are a lot of very practical, nessecary things that were not included on and in this build which would give it an appearence of functionality, practicality, and realism. I recommend heavy ramifications to the train's structure and perhaps even design.
tl;dr the tl;dr: This build needs a lot of work.
Until then, I'll give it a rating of 3/10.
