We consider the open Toda chain with external forcing in two cases, when the external forcing stretches the chain and when the forcing compresses the chain. In the first case, we use an old comment of Jurgen Moser
to show that the system remains integrable. In the second case, we present strong numerical evidence that there is some integrability in the system, but this remains an open and very challenging problem.
