A few more suggestions for passenger trains in Turkey:
Where’s My Train?
Following location of train is possible in Turkey almost for all trucks and buses. Furthermore, TCDD is following its trains by recording all arrivals and departures in every station electronically. Only thing to be done is allowing open access to this information via internet.
Simple and deserted restaurants in trains have some advantages. You can easily find place, spend a lot of time without pressure of consuming lots of things. On the other hand, it’s a little weird that train restaurants are so deserted where long queues are standard in even kiosks of half-an-hour-boat-services. First remarks are: Menu is limited (not running as kiosk), service is insufficient and sloppy.
Mobile Phone Coverage and Internet
Nowadays, it’s really a big problem to be out of mobile phone/internet coverage. There may be some who are happy not to hear any phone ring but trains are not only for touristic reasons. Good to have free WiFi in high speed trains despite interruptions and slowness. Mobile phones are only available only within city limits in other trains.
It’s really a big problem to find power sockets in main line trains. Especially in long journeys, we have many “vital” problems like charging mobile phones/laptops. Sockets in WCs are not good solutions.
I like the “openable” windows in old trains. Neither of new ones has this kind of windows. This is a critical problem for photographers, because it’s not possible to take good photos if window is in between. It would be nice to keep at least one wagon in train with openable windows. That will make it possible for photographers to take amazing photos where taking it from anywhere else is not possible. Trains will be filled by photographers, and social media with photos from train journeys.
