You're asking a multi-faceted question. It's actually also a fascinating question, if you want to do a little word play on it.
We have to understand here that high-frequency rail is not going to significantly increase ticket prices if we compare it to other services around the world. In many cases, actually, high-frequency rail was able to bring sufficient ridership to bring about a decrease.
If we go to high-speed rail, it's a whole new ball game. If you go to Italy or France, you're going to have a two-tiered system. The faster you go, the more you pay with high-speed rail. In that case, it's a significantly important question. Yes, high-frequency rail is potentially going to bring higher costs.
However, one footnote I would add is that we are now seeing the rise of low-cost high-speed rail in Europe, including Ouigo, which is operated by SNCF. It's running high-frequency rail on a low-cost airline model, which is bringing costs down.
That's what we're seeing right now in the market in Europe, and what we're seeing elsewhere in many countries, including South Korea and Japan.
