Luggage storage is just inside each car, and baggage allowance is generous _ 40kg in total, but with height and length restrictions on each piece. Just don't take "hazardous goods, corpses, bones, bone ash and noxious and dirty stuff". However, if you want to take a small pet (including fish or shrimp), that's okay, as long as it's "well packed, free from leakage of droppings".
We were travelling in the standard cars, which have a seating configuration of 2+3. Leg room is generous, and even if the person in front reclines their seat, your neighbour can easily exit without climbing over you. Business cars have even more room, with 2+2 seating. Bathroom facilities are spotless, if a little cramped. Everything operates via sensors - and be warned, it's easy to activate the toilet flush before you're ready!
Stewards come through selling snacks and drinks, and a scrolling screen at the front of the carriage keeps passengers informed of the next stop and the time until arrival. These are also announced in English. The screen also gives the current speed. The fastest I saw was 287km/h but the train is so smooth and stable that it hardly felt as if we were moving.
Chiayi Station is one of the futuristic new above-ground stations en route. Facilities are excellent and once again, efficiency is to the fore. One inconvenience is that the new HSR stations are a long way from the centres of the cities they service. However, if you were flying you'd have to use shuttles, taxis or public transport links to get to an airport anyway.
There is certainly no doubt that Taiwan's HSR service offers a fast, user-friendly, comfortable alternative to taking domestic flights to the cities in the country's busy western corridor.
