Old 1122 switches can be problematic. If you are going to use many of them, take one completely apart to see how it works. They rely on the bottom plate to connect the running rails, and as mentioned the early 1122 versions (which don't need insulating track pins) are configured different from the later 1122E's (which do require insulating track pins). Locos are more prone to stalling on the early 1122's, which is why Lionel changed the design according to their service manuals.
I've rebuilt several 1122's and converted them for fixed voltage input (there is an old thread on that somewhere), but it's probably more trouble than they are worth.
In some cases I have spliced O22 switches into O27 layouts because they have a superior non-derailing action with automatic power cut-off.
