       I have a Lionel 2033 that recently purchased at auction.  Put a
       battery in housing but horn doesn't seem to work.  Ideas?

       Welcome to the forum!
       There is much that needs to be checked to get these postwar
       horns to work properly.
       First, familiarize yourself with the parts of the horn and its
       circuit here.

       Make sure all the parts are there and the wiring is good and
       intact.
       Look over ALL the parts, and insure NONE have any corrosion on
       them. We are dealing with  1 1/2 volts DC here, and the circuit
       must be pristine for it to work.
       Here is the schematic of an engine with a horn circuit.

       After all the parts are clean, you can check out the horn and
       its circuit.
       First thing to do is take a fresh battery and touch the bottom
       end of it directly to the horn casing. Take a jumper wire and
       connect the top of the battery to the horn wire where it is
       connected on the relay. The horn should blow loud. If it does
       not blow, the horn is bad.
       Next, put the battery in the engine and close the bottom battery
       plate and tighten it.
       Now lift up the bottom of the relay by hand so that the points
       make contact. The horn should blow. If it does not, the relay
       contacts may be dirty/corroded and need cleaning and burnishing
       with a very fine emery board. The horn needs to work properly at
       this stage.
       Next in line is to check that the relay is closing under power.
       Put a few lighted cars on the track, turn on the power, and get
       the engine in neutral and lock it there using the 'E' unit. Now
       try the transformer whistle control. You should hear/see the
       relay close, and the horn should blow. If the relay does not
       close under power, the transformer may have a bad whistle
       rectifier and it will need to be replaced.
       Do these diagnostics in sequence until you find out what your
       problem is.
