Please be aware that in some games a minimal route requires a different
train, such as the good trains in 18VA and 1837 (coal companies).
In these cases that doesn't pose a problem because trains are always (18VA)
or never (1837 CC) required, but other cases may be different.
That's why I'm not too happy with linking route existence to specific
trains.
