The New Austrian Railways' Intercity and Nightjet Sleeper Train Interior Design
Sleeper trains make so much sense for travel over land.  They are often competitively priced with air travel, they pollute a lot less and the time saved can be huge when you consider that you spend time travelling when you would otherwise be asleep (although this is sometimes true for air travel, many/most people find it difficult to get quality sleep in economy class).<p>The London - Edinburgh sleeper train (Caledonian Express) has been running pretty much since 1873 and is an amazing way to get between the two cities. You arrive at the station in London between 10-12pm, depending on if you want to have a few snacks or glasses of wine, then wake up in Edinburgh around 8am the next day.
