PMB, I know what you mean about train replacement bus service. On one trip in southerb California our train broke down and we were loaded onto two charter buses. These buses had, like, two inch pads on the seats and the rows were so close together our knees touched the seat in front. (I believe they were repainted school buses)

We went through the 'Grapevine', a notoriously winding up-and-down-hills road on the way to Martinez to catch a northbound train.

We went through cities, stopped at stoplights, tailgated vehicles, swooped from lane to lane, travelling with fairly heavy traffic.

We still averaged just over 60 miles per hour.

I was scared spitless.
