Do you have any other Intercities to add to the thread?
The problem is the definition of 'inter-city'
Did the OP mean 'express inter city services' or 'loco hauled trains that link two cities' ?
If the latter then there are still some Paris - Le Mans and Paris - Orleans clinging on. They (like some other services already mentioned) are 'TER' aka 'regional' so not 'by the book' intercity and not operated by SNCF 'Intercites'. BUT they do link two or more cities (eg Paris, Chartres, Le Mans and Orleans are all cities not towns.
Services Lyon-Annecy and Geneva-Valence are also still (largely?) Corail push-pull.
Geneve - Valence mostly NOT loco hauled now AFAIK.
However there is a large batch of locos and stock based at Chambery. Services radiate to Bourg St Maurice, Modane, Lyon, plus Annecy - Valence , Lyon - Dijon and the remaining Geneve - Grenoble/Valence that are loco

Strasbourg is a comparative hot bed of loco haulage, but not all are 'inter-city' as per may previous comment on the definition: TER200 corail 'Fluo' every 30 minutes at busy times all with 26000. All run Basel - Strasbourg, some extended to Nancy or Metz. There is also a couple of long distance TER along the old Paris - Nancy - Strasbourg line.
Strasbourg - Saint Die des Vosges at peak times and certain other workings on the route?
No very much peak flow only. Out of Strasbourg pm peak, back from St Die or Saales early am peak
My own 'money shot' from a visit last month required an 05.30 start from my hotel in Strasbourg, an early DMU up to Gresswiller, a bracing early morning walk along the line to grab this - the 07.05 departure from Gresswiller (the 06.01 St Die - Strasbourg). Incredibly the loco 67511 is still in original blue and sports
only the spaghetti logo ( a logo which ceased to be the current SNCF logo 30 years ago...). Lovely sunrise light, cherry blossom
and the drive put on the power just at the right moment!
