We rode the Kyo-train from Kawaramachi to Umeda as our means of travelling from Kyoto to Osaka. Having only used JR trains until that point, the Hankyu service was a little confusing but staff at the info office were very helpful. I don't recommend taking luggage on the train as there is no storage available and not enough room to place them near seats. I had assumed a train designed for tourists would accommodate luggage, but realise now that the 'sightseeing train' really is intended for short sightseeing trips.
The train was really hot on the day we rode it. There doesn't seem to be ai-rconditioning, which is a shame.
Otherwise it's a lovely initiative and well worth riding, especially for day trips to places like Arashiyama. The fact that it uses standard fares is a bonus for tourists, but also means that it can get quite crowded as there's no disincentive for locals not to ride it.
