On the White X-Mas heist in Payday 2 there are two trains that have doors that can open with shaped charges.
What are the benefits of opening the trains? I blew one open to go inside, but the only thing I found inside was a Gage package, and one time there was nothing in the train.
Steam user Faildozer has written a very detailed guide, " PAYDAY 2: The Numbers" ("taken from the game files"). Here is what he has to say about ammo packs, supporting your theory:
The ammo bag starts out with 4 uses, some further info about how usage is counted by the game:
- It's not split between primary and secondary ammo; there's just one pool of ammo that weapons draw from
- How much ammo drawn from the bag is based on a percentage of how much ammo you've used so an empty AK draws just as much as an empty M308 which draws just as much as an empty Crosskill and so on
- A default bag holds enough ammo for exactly 4 full refills (400% ammo if you want to think of it as a percentage)
- The Enforcer skill that increases the capacity of the ammo bag gives you 50% more ammo per bag (so 6 full refills/600% ammo)
- The game will always prioritize filling up your secondary first before your primary, so if both your primary and secondary are completely out of ammo, and the bag has exactly 1 full refill left (or 100% ammo) then your secondary will be refilled completely and your primary will still be empty
Medic bags do get used up after 2 uses (without upgrades). Similar to Left4Dead, you die for good if you go down too often, but healing from a med kit resets this counter. So saving them for teammates that went down multiple times already might be worth it.
Here is a guide on how to complete the Framing Frame heist stealthily. I have included videos of each day demonstrating how the execute the plans but remember that each game has a variety of randomised elements which means you have to adapt the plan to your particular spawn.
The Elephant wants you to frame a senator, you're going to do this by stealing paintings that have just been sold from an art gallery, framing them in frames with cameras fitted into them and selling them to the senator. The art gallery has up to nine paintings marked with red sold stickers stickers, get them.
You need to steal at least four paintings. Get the paintings from inside the art gallery to a van outside.
The art gallery has a total of six guards, one of these guards will remain stationed at the front desk unless alerted, and another will remain in the camera room until you breach it.
You will need the following abilities between your crew:
It's best to also get the Camera Feeds asset, and position one of your crew (that isn't responsible for any of the above abilities) on the camera feeds to help mark the guards. Assign another of your crew to scout around on the roof, helping the two breaching the art gallery by marking cameras and guards.
One crew member can breach via the roof if you want but my favourite method of cleaning up the guards is to draw them towards the bathroom at the front of the art gallery (there is a pickable door outside on the way up to the roof) by activating the hand dryers. This allows you to pick off the first four guards one at a time without drawing too much attention to yourself. Bag these up and hide them in one of the cubicles.
Spot the camera in the first hall from the roof before running in, and start clearing up paintings. Throw the paintings up to the spotter on the roof and he can throw them over towards the van.
Move from room to room, spotting the cameras from the roof first until you reach the room that is blocked off by lasers and then exit the building.
Normally by this point you have enough paintings to fulfil the objective but if you want or need more you can have one of your crew members breach the last room from the roof while the two of your crew move the paintings to the van. The spotter on the roof remains in position to catch paintings.
To exit, kill the guard and quickly run over to the van before the pager times out (the Sprinter ability is good for this) and you'll get out without an escape.
If all goes well, you'll be in and out without triggering an alarm and you'll get an achievement - Painting Yourself Into a Corner.

Get the paintings to the buyer, get the cash to the van.
The plan is simple - get the paintings out of the back of your van, into a train car nearby that has a ringing phone in it. Answer the phone to start the deal with the buyer and he will request that you all get into the train car and throw the paintings out through the roof.
For each painting delivered, you will get a bag of cash. Don't throw the last painting out until you've got all of the bags of cash over to the door at the far end of the train car as doing so will start the next section of the mission. Get the cash out of the train car and head towards the getaway van - ensuring that any civilians who see you are controlled quickly, or several ECM jammers are used to stop anybody phoning the police.
If you happen to get all nine paintings on day one, you'll get an achievement once you've completed trading the bags - Big Deal.
Here is a video of day two being almost stealthed:
The objective of day three is to break into the senator's house, steal five of his personal gadgets that can be used to gain access to his desktop computer, use the computer to gain access to the vault, plant cocaine in the vault and (optionally) steal all of the gold.
The paintings you stole on day one have been fitted with cameras, which can be viewed using a laptop on the roof. During the first stage of the heist you will want one of your crew members watching these cameras constantly, marking guards and locating the senator's gadgets.
You're going to break into the senator's house, take out the first four guards and answer their pagers - dispose of the bags on the roof near the start so that nobody will find them. The fifth guard will need shouting down. You can mix this up a bit - if you get an opportunity to shout down a guard in a part of the house that nobody else is going to go, or within a timeframe where the other guards will not be a problem, then do so.
You will need the following abilities between your crew:
There isn't a security room in the house so you can't directly take control of the house cameras. You can, however, melee them to break them and clear yourself a path to the vault.
Find the five gadgets and take them to the laptop on the roof, which will allow Bain to unlock the desktop computer in the office upstairs. At this point you'll need to assign a crew member to use the computer, as it is used to open the vault and also temporarily disable the lasers in the vault.
Once the vault is open, you'll need to turn off the lasers with the desktop computer - these will only stay off for around 15 seconds but they will beep several times before reactivating.
Once you've got the gold out to the vault it should be a simple case of transporting it all to the exit point on the roof. If all goes well, you'll be in and out without triggering an alarm and you'll get an achievement - I Wasn't Even There!

Best Answer
Sometimes you can get the gage packs as you said, another time I've seen an ammo bag inside.
Other than that I'm sure you could probably also get a medic bag in there as well. Not sure about presents though but i highly doubt they'd put a present inside a train that can't be accessed if nobody brings C4.
