While the attempt of cover-up was ridiculous, the event as a whole doesn't seem worse than Spain's derailment that happened two years later, in which many more were killed, and for which all blame was laid on the driver.

Spanish authorities didn't tried to censor the accident, nor did they tried to bury the wreckage with corpses and human remains still mangled within the wagons.

Honestly, with all the censorship forced by the chinese communist party regarding the accident, how can anyone really tell?
In fact, how many accidents have occurred since then that were successfully covered up?
All I'm saying is that your example doesn't make your case that Western governments are that much better at tackling these kinds of potential problems, or that they don't try to cover them up, often in ways that prevent the problem from being fixed.
If you want to argue that they have a train collision a month that we just don't know about, while I vehemently condemn censorship for itself, I can't accept lack of proof as proof that it happened!
