I perfectly know that is still in deployment in all Europe (in Italy for example a Company, created an analizer starting from an USRP * ) , i wanted only to know if you know some "used", "cheap" hardware like BS-11 to buy and start to work on it.

Ex. i saw that this company created many hw about gsm-r... http://www.funkwerk-ec.com/

why old? GSM-R may be old technology but is still in the process of being
deployed all over europe (and other countries). GSM-R is 99.9% like GSM, so
I would not expect much difficulty modifying OpenBSC to work with a GSM-R BTS
(without VGCS/VBCS/NCH/... support, of course).
