Create a logo for Global Peace Train that will Change the World

No words and just a symbol OR Global Peace Train

We are a non profit organization which creates unique marketing focused on creating compelling media, characters and events that share the stories of people and projects that are making the world a better place.

I'd like to explore the following colors:

Aquas: Empathy, compassion, clarity and precision.
Let designers make suggestions:
Dark neutrals: Formality, mystery, exclusivity and luxury.

Imagine a magical train that travels through the dark blue sky filled with stars and galaxies and a mission to liberate all beings from suffering. It travels between earth and infinite other worlds that the mind can make up. It has no limits and it can accommodate all the good and bad in the entire multiverse. And yet the vision is grounded in real social action projects with communities around the globe that are struggling.
Attached:
*The first golden GPT ticket.
*A photo of the front of the train.
*A photo of a piece of art that rides on the train with the blue background and gold stars (we use the dark blue with gold stars a lot to help people recognize our branding)

We would love to see logo designs with:
*A mysterious/sophisticated logo with only a symbol that feels like a special club
*Logos without actual trains in them/A symbol that isn't a train
*A whimsical or magic touch

We want a logo that would look good on the golden tickets (like attached photo) the image that is on the first ticket could even be turned into a logo:
*A key hole that is shining
*The idea is that the train will come out of it and the bright light is the headlight.
*The platform the key hole is on is a set of train tracks that go around the 3d disk.
*On this ticket the keyhole is surrounded by flames
*AND/OR We also use a lot of blue with gold stars in a lot of our branding (see lamp shade photo)
