Today’s shot is from my work at SL. The radios shown in the middle (one with a lit screen) are the Buskom system, our own TETRA radio network in Stockholm, the big one on the right hand side is the old VHF analogue train radio system used by all rail traffic (cityspårvägen and the commuter trains excepted, the first uses Busskom and the others use GSM-R)

So now you can see some of the tools of my trade.
