Well, I don't know you would call the Renaissance Cars elegant.
The Renaissance cars were built in the 1990s by Metro Cammell for overnight service through the Chunnel. When that concept was abandoned in 2000, Via Rail acquired these cars second hand, including many unfinished shells.
The coach seating is very cramped, allowing no carry-on luggage and only three seats abreast. The sleeping car accommodation may be OK, but even that may be cramped. Note that the exterior steps are high with absolutely no hand rail.These cars are also completely unaccessible. I've ridden these coaches at times on the Corridor and they are greatly inferior to the LRC coaches.
