Interesting how both sibling comments (by sofixa and twic) complain about opposite things: that Elizabeth is not a metro service (i.e. it's fast) and the other that it's not fast, it stops at all stations (i.e. it's a metro). It's interesting because both are true: outside of central london is a metro service, in central london is a fast service. The parent op explains it pretty well in the last paragraph: > running a fast long distance service, a metro service and then back to fast long distance.
