Deltic-VS-U.S.A's Big Boy

what loco do you thinks better out of the 2,give a reason and why you favoured the loco you choose

NO CONTEST!! The Big Boy was the biggest living, breathing steam engine ever built. They were built for long distance coal trains. The Deltics were very noisy, smelly tin cans on wheels. Granted, they were fast when they worked, but how many times did they finish a long run on one engine?

I don't think it would be fair to compare these two locos as they were built for different types of traffic the "big boys" were built to haul "VERY" heavy freight over steeply graded track & were capable of hauling 3,000 tons+
& thus were not built for speed.

The Deltics were built to replace 55 east coast pacifics & were capable of 100mph+ but were not expected to haul more than 600 tons or so.

A more appropriate American counterpart for the Deltic would be the Alco PA-series, a passenger diesel that's about equally loved.

Going by the remark above saying that a deltic was a tin can on wheels
I think it was a bit more than that with having
a maximum tractive effort of -222kn {50000ibf}
weight of 100t
and a engine of two napier-deltic D18-25 of 1230kw {1650 h.p} each at 1500 r.p.m and main generators two english electric 829/1A its still one of
the best diesel locos the world has seen. and it still has a big amount of fans

dunno bout that...it did the job but was very expensive and therefore not very efficent in those terms. Id say the HST power cars are higher on the list of the best diesels the world has ever seen....as passenger units, they are probably at the top of that list.

As someone who likes big, loud, powerful, overpowered and most importantly obsurd machines, I love the Deltic more than anything else, like, ever.

Wearing a suit behind a desk, a Deltic is a bad idea. In terms of giving me fits of giggles? Deltics rule.

I think the latter is most important.

Deltics were noisy even if you were sat in the cab.

They were always noisy.
