Society is not a business. Markets are a useful tool that societies use to optimize certain kinds of capital allocation and goods production, where that makes sense. No more no less. Most of the things societies value most highly don't fit into the market hole. If trains were exclusively a mechanism for capturing or avoiding carbon, then the metric of $ / tons would be valid. Trains very obviously are not that.
