I was searching for something else, and came across these.  PS Murrabit has not been preserved.  PS Ruby, the bridge at Murrabit, and PV Kulkyne, have survived.

The links didn't work for me 

However, I believe that the Murrabit's wheels are the ones currently propelling the Ruby.

J.g.Arnold wheels n gears are on Ruby

links don't work for me either

The links are now fixed.
Some software demands <> markers, or urls split over multiple lines.
php software hates <> markers, and I have just edited them out.

It was broke, so I did fix it.
