4-6-4-6

The 4-6-4-6 locomotive was a proposed locomotive with an unknown designer.
==Plans for it==
It was going to share the same wheel layout as the Pennsylvania Railroad Class Q1 with its rear cylinders Mounted next to the Firebox much like the Pennsylvania Railroad Class Q1 and Baltimore & Ohio Class N-1 it was going to have a four-wheeled pilot truck on the front and a six-wheeled trailing truck on the rear, it was also going to have streamlining built into it which was unknown at this point on what it was going to be designed by if it's streamlining was going to be designed by Raymond Lowey or someone else; The 4-6-4-6 Locomotive would also feature the more American looking Boxpok driving wheels and the more conventional Walschaerts Valve Gear, which is used a lot in the United States of America.
==Reasons to why it wasn't built==
Some of the reasons could be that the Q1's & N-1's Rear Cylinders were placed beside the firebox which meant that it would limit the size of the firebox for the Locomotive, thus making the firebox have a poor draft and thus making a railroad or company (owning the locomotive (had it been built)) go through the hassle of fixing that one issue. Another reason to why it wasn't built at all was because of one problem/flaw that occurs on Duplex locomotives, which is being prone to wheelslip, which is a bad move when it comes to duplex steam locomotives.
==Trivia==
*Not much information can be provided about this locomotive's wheel arrangement.
*The locomotive could have been proposed for the New York Central Railroad due to the similar streamlining to the NYC Hudsons.
