(Warning: Initially I resisted posting this mashup when it was suggested to me but it appears that other blogs are testing it and deciding it makes the grade. I will warn you that if you're using Firefox version 1.0.1 or any version of Netscape, don't bother trying to view it. Upgrade to the latest version of Firefox before clicking on this link. I want to expose people to the latest and greatest Google Maps mashups, but I don't want my links to crash browsers and make people angry with me. Now, on with the show...) --> Google Maps + NYC Subway system - This mashup takes ALL 400+ subway stations and plots it on Google Maps. There is Station Info popup markers and you can search and plot multiple addresses. There are only 2 zoom levels on this one because of how much data needs to be re-plotted each time you zoom in.

Thank you Mike for the link.
As you report, it is true that the loading of the map can be slow, and is troublesome this way for the earlier releases of Firefox.
The problem seems to stem from the way google has writen the addOverlay function. It forces an update of the map each time a marker is added...and with 400+ markers for all the subway stations, that adds up to a lot of load time. Hopefully google will modify the core sofware to provide a way that you can plot numerous markers and then redraw the map only once...hopefully.
Never the less, while the stations are loading it is possible to move the map around and zoom in...even if the redraw is a little jumpy.
Also - there are now 3 zoom levels, and I hope to get to add a few more over the weekend. I also hope to add a feature which will allow other sites to put an address in a link to the map, and have that address plotted when the map loads. This would be great for businesses, restaurants, personal sites.
You can get information about upgrades to the map here (without loading the map itself).
Thanks again!

Just want to say - that thanks to Lokkju at the google maps api group the NYCSubway map now loads blazing fast in Fox 1.0.4 and IE6!!
Not sure about performance in Fox 1.0 but its probably fast there too.
Check out this thread for a script on loading hundreds of markers in a second.
