Going to Glasgow, the train splits at the junction town of Carstairs, while all the other routes split at Edinburgh. (That includes the Fort William route, which then goes through a different station in Glasgow.)

Unless you've booked a seat instead of a room, you won't need to move during these splits — but you might wake up.

Euston has 16 platforms and is often very congested — but it was much quieter when I arrived around 9:30 p.m.

If you're traveling further north than Edinburgh, you can board an hour earlier than this.

The Caledonian Sleeper differs from most British passenger trains in using a locomotive similar to Amtrak.

It's supposed to make the journey smoother for passengers, but I still struggled with the shakiness.

The staff member at the desk was friendly and welcoming as he gave me the keycard for my room.

There were some complimentary drinks and snacks, or you could also buy meals.

I watched the news on TV and had a can of Irn-Bru, a soda that outsells Coca-Cola in Scotland.

The Caledonian Sleeper uses British Rail Mark 5 passenger carriages, which entered service in 2019, so they're pretty modern.

Prices for a room start at £200 (about $250), but can be more expensive depending on when and where you're traveling.

If you're looking for more space, there is a double-bed en-suite option — but you'll need to book well in advance.

Families could also book rooms with an interconnecting door. Tickets for children under 16 are slightly cheaper.

The operator says each guest can have one piece of hand luggage and two larger items no bigger than 30cm x 70cm x 90cm.

After filling out the breakfast order form and choosing a time to eat, you hang it outside your door.

The amenity packs include a sleep mask and earplugs.

It wasn't easy to keep my balance in the tight corridors when the train started moving.

It's reserved for those who booked a Club ensuite or Double room, but if there's enough space, you might still be allowed in.

I was impressed with the staff, who were both friendly and laid-back.

I chose a seat facing the window and perused the menu.

Haggis is made from sheep's organs — but is tastier than it sounds!

I'd never showered on a moving vehicle before, but I didn't have any trouble doing my ablutions as the sleeper train slowly pulled away from Euston.

The temperature control came in handy at night, while the host-call button, connected to a speaker above the window, can be used to order room service.

The upper bunk also has a light switch and one USB-A outlet.

The mattress and comforter were good quality, but I think I should've chosen the top bunk as this might've been less susceptible to vibrations and shakiness.

Throughout the night, my attempts to sleep were disturbed at the four stations we stopped at, and I couldn't help opening my eyes.

Once the train started again, the shakiness made me slide down or sideways in bed. Although headphones helped me block out the worst of the vibrations, they were still noticeable.

I don't think I really fell asleep until around 4 a.m. Then, I woke up again as the train divided at Carstairs.

Like my dinner the previous night, my culinary expectations were exceeded — I thought it was a first-rate bacon roll.

I also got a carton of orange juice and sachets of ketchup and brown sauce.

There is supposed to be a table that folds out from underneath the sink. However, mine was missing.

I had plenty of time to get dressed and pack my bag.

After arriving in Edinburgh about 7 a.m., almost an hour passed before a member of staff knocked on my door, shortly followed by an announcement asking passengers to leave.

Edinburgh Waverley station is on the city's main thoroughfare, Princes Street.

With a couple of spare hours, I was able to take in the view from Calton Hill, visit Greyfriars' Kirkyard, and spit for good luck on the Heart of Midlothian mosaic on the Royal Mile.

I might not have had than a couple hours of sleep, but I found a second wind of energy from the beauty of the city — or maybe it was just the cold weather and pending work ahead.
