I always look forward to your posts.
What was the reason for using flexi oil trucks?
Did the flexicoil trucks track better on uneven tracks?
ctr,
Thanks.
By no means am I an expert on truck design but here is what I can say:
The longer (9-foot) wheelbase of the 4-axle Blomberg trucks distributed the weight on the truck over more ties and a longer piece of rail than the (8-foot) Flexicoil trucks. This improved the support of the truck, reduced the stress on the rails and ties, and was better for operation on lightly-constructed sidings, yard tracks and through turnouts. The Flexicoil truck had coil springs between the truck frames and the bolster, and was stiff and produced a hard ride. On the Blomberg truck, the transverse leaf springs and visible swing hangers outside the truck frame allowed lateral motion that improved the ride and enabled the truck to operate at higher speeds.
