We discuss a new method for the production of trains of FEL radiation pulses based on the FEL emission driven by a comb-like\udelectron beam. In addition, we present recent experimental results on the two color FEL emission as generated at the\udSPARC_LAB facility: a train of two short (<200 fs) electron bunches, almost overlapped in time, with a comb-like energy\uddistribution, has been injected in the undulator, giving rise to FEL pulses at two characteristic frequencies with multi-peaked\udtime structure. This scheme shows also the versatility of the SPARC photo-injector to generate and manipulate such energy and\udtime distributions
