The Brignais terminus (bottom centre on the map above) ...
Fortunately, correspondent David can use this link to get to the third branch which will take him back from Lozanne to Lyon St Paul; the third branch in this little tram-train-tram network.
In fact it is two single cars joined together shuttling back and forth.
At Tassin, we find the depot and works for the trams, about which the launch brochure is equally effusive.
**weekended. A term used by David (and others in the trade) to describe being stuck in France (etc.) for Saturday and Sunday. Because of drivers' hours regulations, you are required to have a two day weekend off every fortnight. So if your schedule is awry you are stuffed as David was at L'Arbresle for a wet Saturday and Sunday.
But David's distress is our advantage as he could rin the mini-network and brief fbb on what was happening.
