SP Daylight

[ericsp]

Does anyone know what the average horsepower per car for any of Southern Pacific's Daylight trains? The San Joaquin Daylight would be preferrable.

Diesel. About the late 50s to the early 60s.

QUOTE: Eric, all you need is a photo to calculate it. 1500 hp for an F unit, 2000-2400 for a E unit or PA. Figure 50-60 tons per car. I expect you'll find a ratio of 5-7 hp/ton.

Thanks. I have heard that SP did not paint any F7s in Daylight scheme. I am guessing they were bought too late to be painted in the Daylight scheme.

The F's and E's were contempories. The Daylight was the SP's passenger scheme, The F's were painted in the Black Widow freight scheme. However, the Saint Louis Southwestern (Cotton Belt) did have a F in Daylight. 1 or 2 E's were in Black Widow for a while.

I have seen pictures of SP F7s pulling passenger trains. So, did SP originally buy the F7s for freight and eventually decided to use them for passenger trains? Also, did SP's F7 come with boilers? If not were they added when SP put them in passenger service? Thanks for the help.

The F7s were bought for freight,but some were equipped with steam boilers for use on secondary passenger trains.The FP7s were bought for secondary passenger service.After the PAs and E units were retired all trains were pulled by either F units or SDP 45s.

The first link has some interesting photos on their website.

If you enjoy history you should look at some of those pics. [;)]

Both sites have fantastic photos. And on the second site, sure is good
to hear "City of New Orleans" playing. Even if it is just an instrumental!!

I looked through the pictures on http://www.snowcrest.net/photobob/sppass.html . It looks like one F7A and two F7Bs were pretty standard. I saw consists as short as five cars. On the long consists, it is difficult to count the cars, but I counted at least 12 on some.

Figuring 4500 HP, that is 375 to 900 HP/car, and figuring that cars weigh 60 tons, it is 6.25 to 15 HP/ton.

By the way, the Fresno Yard is full of tankcars in the photo at http://www.snowcrest.net/photobob/sj23.html . I wonder if these cars are carrying wine. I would think most crude oil would be traveling via pipeline by then. To my knowledge there has never been oil refineries in or around Fresno, nor can I find evidence of much industry that would have used much chemicals. There many wineries in the area though.
