With all due respect, I don't think any "ordinary" users of the line could care less about whether the train they're about to catch has done a full day, half day, or only manages one round trip at a time without going for a bit of a rest. Most of them probably wouldn't even give a thought to how much money may or may not have been spent to get that train to turn up. As long as it does. Which, it would appear, the 230's are managing to do now. For all any of us know, the 230's may now be capable of managing a full day. But they're not currently diagrammed to do so and until they are, we'll continue to not know.
