In my house with a two-pipe, vacuum/vapor system....

In my house with a two-pipe, vacuum/vapor system, a second floor radiator was removed some time ago. Both the feed and return pipes were simply capped. At the start of the heating cycle, there is knock in these pipes (which seems to be getting worse). I checked out everything else (clean water, pipe tilt, insulation, etc) and all seems well.
Could be the way they are capped, or something else to do with the removal of the radiator?

Noise?
Is it possible that the pipes were pushed down below the level of the floor, and are now tilted, and this has caused water to be trapped?

Is the hammering
in these risers, or in something else connected to the risers? Possibly a bad trap on an adjacent radiator?

Steam.Head -- thanks for the reply.
All radiators get very hot, completely across. I thought this means the traps are working. Am I wrong?

Mike --
The caps are above the surface, and the pipe slope/angle in the basement seems to be okay.
Since the hammer is VERY early in the cycle (1st 5 minutes or so) in teh feeder pipe, I am thinkling the pipe might be clogged or something, preventing the condensation from completely flowing back (but do not know how to check).

It might be a clogged wet return
which causes water to back up into the steam main, causing banging.
