The other logistics are fairly easy to get out of the way. If he wants the train to stop at his location he'll need this set-up for a station... Here's the title of the manual for how the generators work... Here's how they're expecting to get correspondence back...

Cam swishes his tail as he makes sure everything is squared away.

Do they have anything else pressing?

"Would you find it convenient to have some sort of immediately demonstrable diplomatic gift for curious parties, or anything, before we go?"

"Yes, very much so."

"What would be suitable?"

"Some form of technology we don't have, preferably apparently harmless." She thinks of speculative technologies. "Can you do - like a screen but in three dimensions? Something that will entertain the ministers, but not make them get ambitious."

"Yes I can! Kinda content do you want me to load it up with?"

"At least one very obviously foreign film. If you have anything you'd recommend that'd give a sense of your culture even without a shared language..."

"Ooh, good question. There's kind of a wide spread of cultures. I guess I can just go with 'Atriama' and maybe a few years worth of the pre-drama Curator's Symposium? That's mostly music and dance, should be accessible through the language barrier."

"Should be interesting, at least."

"Do you want a little portable projector or a big stationary one?"

"Portable would be of more use, I believe. I'm often in different cities."

He makes her a little projector with wheels, already turned on and playing the overture to something performed on a circular stage. "There you go. The battery will last for a while, depending on how urgent other things turn out to be I might have managed to rig up something to convert local electricity by the time you'd need it recharged but if I haven't I can just swap the battery."

"Alright. I'll avoid running it constantly. Thank you; how do I operate it?"

Cam hands her the remote, which he has made without symbols on the buttons; he adds those in local characters as he explains their functions.

She tests them. "Fascinating."

"Glad you like it!"

"Indeed."

If there's nothing else, she'd like to go start on the assorted logistics on her end. And the politics.

That seems to be everything! They can get back in the shuttle and go find their snowfield. Cam brushes up on architecture on ice foundations.

It looks like there'll be some solid ground, especially if they decide on a heat generator, but there'll probably be permafrost and rock involved even then.

Snowfield: easily findable, with two railway tracks a bit apart running across it. No trains right now, and the tracks are elevated somewhat, and entirely free of snow and ice.

"Any requests for the initial building?"

"I don't care."

"I'd like a room with windows."

"You are people of simple tastes. No complaining if you don't like how tall I make the ceilings or something. Okay, I'm not sure how to get us hooked up to plumbing here so I'm just going to do a reservoir and a deep septic..." He mumbles in this vein while fiddling with a design on his computer.
