::"This junction is used for TGVs going to Lille-Flandres. All TGVs and some Eurostars stop at Lille-Europe. Non-stop Eurostars pass through a tunnel under the city of Lille at 200 km/h." Some TGVs go through L-Europe while those terminating at L-Flandres dont< so surely not all TGV on LGV Nord stop at Europe. Also there is no separate tunnel for non-stop Eurostars, they go through L-Europe and simply dont stop there.
