It was a place of brothels and street prostitution, strip clubs, drug dealers and runaways.
Things have changed a bit over the years. Its become a bit more upmarket. (see this article from ABC News) Attitudes have altered somewhat and brothels are legal in some circumstances but.... it still has a bit of a reputation.
I was really surprised to learn as I grew up that there was a Kings Cross in Britain and more surprisingly that it wasn't the centre of the prostitution in London. I do confess though that I still thought twice when booking accomodation in Britain when the recommended hostel was at Kings Cross! Harry Potter helped enlighten me somewhat and then it became a must see destination.
London 2010 I visited the famed station and found platform 93/4 with my two older children aka Fangirl and The Beast
Kings Cross or in this case Kings X is also a traditional quilting block (and not a hint of redlight or trains about it - although it does resemble the sign for railway crossing)
As is to be found with traditional blocks there are a few variations on the block all called Kings Cross.
The pattern for this block came from Quilter's Cache here
I didn't have enough of the dark blue spot to make all the units so I substituted another fabric as close to the original as I could
When the blocks are put together into a quilt a secondary pattern emerges.
