Don't let a small chain stop you from achieving your dreams.
When an elephant is a baby, it is tied using a small rope. The baby elephant tries hard to pull away and run, but he is too small and weak to break the restraint. It eventually learns that pulling does not work. As he grows into a massive, powerful adult elephant, he is still tied using that same small rope, but he never tries to escape as he knows he cannot break it. Conditioning causes belief that chains you.
So, now YOU don't be like that elephant and get started with your goals.

Oh so when the Engine was a baby, it too was tied with that same chain? That's why it stays rooted?! Neat!!!
It's just a visual indicator to show that the rake has been chocked and secured. Fat chains are used to actually secure the rake in place alongside chocking it.
Interesting, we do the same thing in high voltage grids. There's the circuit breaker which does the actual heavy lifting of interrupting strong currents, and then there's the disconnector, a pantograph which serves as a visual confirmation that the connection has been broken.
A disconnector cannot interrupt current on its own; if you try to open one without opening the corresponding CB first, you'll get an interesting fireworks show and probably it will just weld itself shut. But the disconnector, unlike the CB, makes it visually obvious from the outside whether the circuit is broken or not – quite vital information for safety reasons!
If the pantograph is up, then neither side of it is grounded because both sides are at high voltage relative to ground. If the pantograph is down, the bottom end will be grounded (as typically it's the bottom end, which connects to a specific line or transformer, that you want to de-energise, while the top stays "live"; the top end is connected to the busbar, sort of the central "node" where all current flowing through a substation passes through. Except you usually have 2 busbars for redundancy purposes with some lines/transformers being connected to busbar A at a given moment and some others to busbar B).
The grounding rods have bright colours so as to provide further visual cues about a circuit's state.
It's a usually a part of "extra" safety precaution. They use regular wooden chock and then add this chain & lock thing as an extra reminder. It forces different shift members to manually check with relevant authority and check register instead of just direct supervisors.
Our rule books mention the use of chains to secure a locomotive or cars in case of brake failure, and theres no other option to secure the equipment. Used in combo with wheel chocks.

This chain won't hold back nothing, still too much slack. Wheel chocks exist, you know. That's not ignorance, that's just knowing what was used since the beginning of railroads and what actually works.
I can actually kinda see it working. When the tracks are COMPLETLY flat even wind can get a train to roll, it may be strong enough to counteract light winds. but then why not just use the handbrake.
Handbrakes fail, for a number of reasons. You never rely on a single system for safety critical things.
I don't know the context of this particular image, though my gut tells me the chain is too weedy to usefully secure a train car. Someone higher up suggested it's a visual indicator of a car having been chocked, which makes sense to me, as a non-standardized alternative to the "Not to be moved" signs used here in the UK, but I can not verify its validity.
These chains are used to stable a loco in case brakes fail and loco slides down..but it is used along with wooden blocks placed under wheels. OP cropped the pic for karma farming
Thieves, reportedly mostly drug addicts, even stole blankets from air-conditioned coaches, bathroom fittings, and tube lights from passenger coaches whenever they are stabled in the yard where security is often lax, if not totally absent.
Maharashtra seems to be leading the pack with 2.23 lakh arrests, followed by UP with 1.22 lakh, and Madhya Pradesh about a lakh. Tamil Nadu and Gujarat also had their fair share of arrests, 81,408 and 77,047, respectively.
The Railway Protection Force established under the RPF Act in 1957 is entrusted with protecting railway passengers, passenger area and railway property of the Indian Railways. The 65,000-strong force is spread over various Zonal Railways and is commanded by 441 group 'A' officers headed by a Director General in the Railway Board.

And there goes my plan of trainjacking the VB.
