The Empyreal Trains

The Empyreal trains run as the main fast transportation between major cities, but are geared towards the upper and middle class travel. They are very popular though there are many rumors that they are actually dangerous by older people who aren't fond of the relatively new (in the last fifty years) invention. However, while trains do derail and always make the paper when they do, which can make them seem dangerous, its actually a pretty rare occurance and trains are quickly becoming part of normal travel between cities, easily cutting down the time that it used to take to travel across the county.

The Inner Workings

The Empyreal Trains run on a combination of solar and lunar energy. The spell circles, carved by knowledgeable Empyreal engineerings on the top of the front locamotive, take power from the light of the sun and the light of the moon in order to generate thrust forward. Each spell circle allows the metal of the train to absorb and store the light of the moon and light of the sun as energy like an empyreal mage naturally does, but if the train only has one (either a solar or a lunar), then they can only travel with the magic in the day or at night. Trains that have both are usually more expensive because its more expensive to carve both. as it requires more material, more time and more workers, and because the trains that have both store more energy and thus can make the trips faster.
This energy doesn't power the engine but rather a spatial spell circle on the front of the engine that allows the train to travel along more space than its actually travelling. That is the spatial spell circle can shrink the distance in front of the train sort of like folding space, though not visibly. The train just appears to be going very very fast.
When the train runs out of solar or lunar energy to power it, it goes to the steam engine instead and the remaining travel becomes much, much slower. The average speed of a long distance train is 100mph on steam engine and a little more than double it when the spell circles are active at 250mph.
The trains rarely run the spell circles the entire trip, even if they are only running during the time the spell circles can absorb light. (that is helical circle in the day for example). This is because the train needs time to aborb enough light to run the spatial circle for a reasonable amount of time. Saving energy also allows the train to run at the opposite time (that is a helical circle train running at night) and still be able to use the spatial circle.
The spell circles are activated and deactivated with a lever inside the control room which pushes in and pulls out a tab that when pushed in, completes the spell circle activating it automatically.
Helical trains are generally faster than lunar trains, because they aborb more light than the lunar trains do and more consistently. (After all a lunar circle can't exactly absorb light during a new moon). Thus the order of expensiveness and speed of trains goes: Celestial trains (ones that run on both spell circles), Helical trains (just sunlight), and then lastly lunar trains (just moonlight).

The Inner Designs

All Empyreal trains are split into a first class and a second class sitting area, but the Celestial Trains are also have a front caboose, just after the front locomative, that's designed for the wealthiest of the wealthiest and is a private room for those wealthy enough to afford it. This amounts to very few, very powerful families that have exclusive access to this private caboose.

The Private First Cabin

Designed for luxury for the noblest and wealthiest of families, the First Cabin on a Celestial Train, is line with carpets and the seats are all cushioned with a nice low coffee table next to it (bolted to the ground). The room is designed to look like a withdrawing room in a noble families townhouse. It's not a large space, but its not a small space either and there's plenty of leg room and space for a good sized family of six to sit around and enjoy the train ride. Windows line the walls on both sides of the cabin
The first Cabin gets first access to the train attendants service and can order any food or drink that the train can provide. While this isn't usually a hot meal, it is often very high class cold meals, such as charred corn and goat cheese avocado toast or things like a pineapple mago salsa chicken lettuce wraps. Often the service to this cabin will utilize foreign fruits and vegetables or fresh fish and other hard to perserve items as a sign of the effort they are making to provide comfort to the families. These hard to perserve items may be available to the first class as well, but the First Cabin gets first choice. The train attendants will also provide almost any drink of choice including any alcoholic drinks for the travels.
For long distance travels, the train also provides space to sleep to the First Cabin, though these accomodations may be tight and not as appreciated. These accomodations are generally only in trains that make distances long enough to require them or in trains that run at night, and take up the entire second caboose.

The First Class Cabins

Designed for luxury but much smaller, these cabins are often private areas for a traveller to rest. They generally aren't built for families but families can be accomodated. These cabin spaces usually look something like small study areas, with a simple, but comfortable bed for laying down, a padded reclining chair with just enough space to fully recline and still have enough room to get around the cabin, and lastly a desk and chair bolted to the ground to work at. These are generally designed with businessmen in mind as they are usually the ones who will use these cabins. There is just enough space in this cabin to get around comfortably and not feel squeezed in, but the rooms are not large. The room is closed off from the rest of the train and a blind can be used to close the window on the door for privacy.
When families travel together, generally, each member of the family gets their own cabin and parents will bring along a nanny for small children to stay with them in their own cabin. However, generally speaking, families will use the Family Cabins in the next section instead.
Train service will go past these rooms and knock on the doors offering food and drinks, but the First Class Cabins also have the option of leaving their cabins and going to the small bar on the caboose just after the first class cabins (there's generally 4-6 first class cabins on each caboose. An expensive train may have two or three cabooses devoted to the first class, while a less expensive one will likely only have one and will forgo the small bar caboose). The small bar has open seating, and is only accessible to the first class and to the family cabins. The small bar offers food and drink and a place to talk with other travellers

The Family Cabins

Not often as luxurious as the first class cabins, generally the family cabins are individual rooms, with two rows of padded seats facing each other, for families to sit together. While its not as luxurious, it is more expensive than the general sitting area and usually only wealthy and upper middle class families can afford the expense for these private rooms for their family. There are usually 8-10 of these in one caboose and generally speaking, there's only 1 or 2 of these on any train, expensive or not. For some inexpensive trains, the family cabins are the first class. On trains that have a bar, the family cabins also have access to it. It is usually towards the front of the cabin from them and the split between the family cabins and the first class cabins. Generally speaking the family cabins do not have access to private train service and if they wish to eat, they must head to the bar to do so.

General Sitting Area

This makes up the rest of the train and can be anywhere between 5-7 cabooses of it. The general sitting area is lined with back to back seats (like booths) all the way down and on both sides of the train with a singular path thorough the trains in the center. These spaces are open and there's no quiet private space, other than you are in a booth. There is no food service to the general sitting area and food must be carried on with them. Generally only the upper and lower middle class can afford the ticket to board the train, even in the general sitting area.
