Narrative:

I received a phone call at home from a maintenance supervisor who informed me that a 'junction box;' which sits underneath the right main gear truck was damaged by ice and snow. He was interested in our landing runway and taxi route to our international gate. He was going to file a complaint with the 'city' to prompt them to get the taxiways and runways cleaned off better. He felt that we had hit some ice and snow on either the landing or taxi in. He also mentioned that he has seen about 20 of these junction boxes damaged and it usually occurs when landing on a snow covered runway. He placed no blame on the flight crew.I provided our landing runway and taxi route to our gate. The runway itself was completely cleaned off and in good shape; but the taxiways had some areas of deeper snow. I have no idea where exactly the snow or ice was high enough for us to hit this junction box. As far as the flight crew was concerned the landing and taxi in were totally normal. I agree completely with the supervisor that the city could have had the taxiways in better shape; but in fairness to them; they were recovering from an earlier snow storm of epic proportions. The 777 has a wide main gear and there is not much leeway on deviations from the center of a taxiway. Maybe they just needed to get the taxiways cleared better near the edges.I was completely surprised to receive this call as the landing and taxi in had seemed totally normal and we had no indications that this might have occurred. Also; I have attempted to contact my crew to advise them of what happened in case they would like to file their own report. I would like to add that all three first officers were extremely conscientious and were totally in the loop for the landing and taxi in.
