I've been reading some news and some trip reports about the 1 train operation of SUF at SFGADV. After checking out RCDB.com I noticed that SUf at SFOG has 3 trains but the SUF at SFGADV and SFAM only have 2. Is this because they have 2 stations. So they can unload load and dispatch the 3 trains at the same time. So why one is unloading one is loading and one is heading out. Also I've don't think I know a B&M off the top of my head other than these 2 SUf that have 2 trains. Do you think they only got 2 cause they could be expensive so they only opted for 2?
This allows for a 3 train operation, as two can unload/load at once.
However, often at SFOG, the third train manuevers the short course so quickly that it typically ends up stalled in the final brake run while ops finish up unloads/loads and dispatches.
Because it was the first, this problem was addressed with future installations and a the dual station was omitted as was the unnecessary 3rd train.
I believe SFOG's may operate with 2 trains more often than 3.

Actually quite a few only run two, like the Dorney Park B&Ms. Is that even what you wondered or did you mean just the flyers? *** Edited 6/6/2005 7:50:31 PM UTC by eightdotthree***
As for the third train being unnecessary....well, let's agree to disagree on that one. I like the idea of having a spare train, I'd hate to be forced to go to one-train ops on a busy Saturday should something unforeseen happen.
Presumably the dual station was in case the load times were off the charts (like they are on the Vekomas) - then they could double load. Fortunately, B&M designed the restraints so well, that it doesn't take much longer to load a train as it does for one to navigate the course. Thus, the second station and third train become redundant (ala GAdv. and GAm.).
It might also be of interest to note that the GAdv. and GAm. models have 8 row trains instead of 7 row oG trains and the track was slightly modified to accomadate the heavier trains.
SFOG's Superman was running two trains the last two Fridays despite small crowds.
I can speak first hand on 3 train operation and two stations. Having them definately decreases the wait time and is much more efficient than having 2 trains out of one station. At SFOG we only run two trains during the week because we have minimal crowds. The number of operating units on a ride is based on the park attendance for that particular day, so unless there are special events that bring in more guests than normal, during the week SUF at SFOG will almost always run no more than 2 trains. However, on Saturdays, our most busiest day, we will almost always get up to 3 trains sometime in the afternoon because the crowds permit it.
Having 3 trains and 2 stations is alot more efficient because it is actually alot harder to stack trains than with 2 trains out of one station. With 2 trains, it's easy to stack because the ride is so short, and one train doesn't actually start loading until the other is in the pretzel loop already. It is possible to not stack trains with 2 trains but it requires a lot of help from you, the general public. The general public is the main reason trains are stacked anyway. We tell you to secure all loose items before boarding, we tell you to take off your flip flops before sitting down, we tell you to board the train as quickly but as safely as possible, and once you get there you're still confused about how to strap in and unaware that your legs go behind the flaps, eventhough you've been standing in line watching everyone else go before you.
Like I said, with 3 trains it's a lot harder to stack trains because you have so much more time to load. With 3 trains, train 2 is being unloaded, train 3 is being loaded, and train 1 is going up the lift, by the time train 1 hits the pretzel, train 3 is being dispatch and train 2 is being loaded. by the time train 3 hits the pretzel train 2 is being dispatched and train 1 is being unloaded, so there's a constant motion, a constant dispatching, a constant rotation, which makes it very hard to stack trains when running 3 of them on SUF. Sure it does happen, when the operator is overwhelmed with issues. For instance, when the operator has to call out seats that are still unlocked, direct employess returning from break to their positions, the phone keeps ringing, and you have a guest staring you in the face about a phone they lost on the ride, when all that is happening at the same time, of course dispatching will be delayed and the 3rd trian might stack. And you have the issue where people can't fit and won't get up and refuse to leave. Also sometimes the ride may cause stacking. For example, the locking and folding up of the seats is controlled by a radio signal, and sometimes the signal gets lost just like a cell phone, and we have to wait for it to return before we can dispatch, which causes delays as well.
Just as a side note, with one trian SUF can run up to 476 people, with 2 trains up to 980 people, and with 3 trains up to 1260 people, so it's safe to say that 3 trains and 2 stations are far from useful, and a lot more efficient. Sure it may be more maintenance to upkeep 3 trains but in the end, it is worth it, because if one train is not operating, you still have two left that you can run. And that's another reason why SFOG only runs two trains during the week. Every night they switch a train, so if on monday they run trains 1 and 2, tuesday they will run 1 and 3, then wednesday they will run 2 and 3, and so on. This allows them give each train operating time and to fix problems on a given train before the weekend comes, when all 3 trains will be operating.
With one train with 4 direct operators it is up to 420 people, two trains with 7 direct operators is 840, 3 trains with 7 direct operators is 1120.
With one train with 5 direct operators it is up to 476, 2 trains with 9 direct operators it is 980, and 3 trains with 9 direct operators is 1260.
So like I said, the numbers didn't come from my head, B&M set them
I understand why a park would not want to staff more people to run 3 trains when the crowds only justify 2. It just costs more money. But what I don't get is running just one train with light crowds. If there is a second train, why not use it too? It does not take any more people, they just don't stand around as much. The only things I can think of is wear and tear on the trains and the power to take the extra trains up the lift. Is it really that big of a deal? If a station fills up due to a one train operation, the line might not spill out into the switch backs, but it can still be a long wait with one train leaving every 3 minutes or so.
The manufacturers DO in fact specify max. capacity, but meeting those numbers rarely occurs in the real world, where people think it'd be fun to have their oversized plushy take a ride with them...;)
Two trains ARE more costly to run than one, but it'd have to be a really SLOW day for me to decide to save money that way...making people wait in slow-moving lines, IMO, is one of the worst things a park can do. The results are clear: Grafitti, litter, line-jumping, sitting on railings, are all DIRECT results of slow-moving lines...and NOT good results.

Seriously though, for two of your MAIN money-makin' parks, go ahead and splurge on the third train....eventually, you'll be glad ya did. ;)
So given the numbers, why is 2 trains higher than twice 1 train?
