There is no separate Wirral Line station, it's considered part of Lime Street, but the X location marks the underground Wirral Line platforms pretty accurately. And yes, there is access from the W side of Lime St, at the S end of St George's Hall, as well as access from the main Lime Street concourse.
Merseyrail refer to it as Lime Street Low Level & IIRC so does signage inside the main train shed.
Fixed the SE end of the platform from the lengths and angles of the route from the lift, then found this matches a slightly wider feature showing on OS OpenData Streetview, so the platform should be pretty good now. Estimated the more southern escalator + subway route lengths and angles and hence the underground ticket office. Didn't walk the escalators+stairs+footway to the middle of the platform, although it can be accessed without a ticket via the lift and platform...
Now you've made those tweaks I'd think the platform doesn't extend so far under St George's Hall. The ticket office is also a convenience shop or newsagent called M to Go, see http://ratings.food.gov.uk/business/en-GB/498395/.
Added shop details. Yes the surface level platforms elsewhere on the line are 100+m long, but the loop tunnel stations probably minimal length to take the current (~60m) and planned (~80m) trains. Truncated NW end to the wider feature on OS streetview, shifted the main access way back E a bit.
Turns out the stations accommodate double length trains (2 x 3 car coupled together) so 120m - saw one, it just fits. Estimated lengths and angles for the platform access ways, are 2 nearer 1/3, 2/3 points with up escalator for one.
