They are called track ends, and if you go to the tracks option in Surveyor, and then select the centre of the 3 options, you will find what you are looking for in the list.
Searching the DLS for 'Bumper' brings up about 20 options including some nice US style ones by LLJ. Make sure you have the early version 'Trainz' ticked off on the search options...
Some do, but most will only stop something going at 13mph (or maybe it's kph) and some have a slower limit than that. If they go too fast into the terminating device (whatever's stuck on the end of the line basically :hehe then the whole train will just derail.
In my surveyor options, they are also listed as a rail end. It's my understanding that they also act as a red signal. So don't use a signal and a rail end close to each other.
The one I use the most (railsend from the VMD site) shows up as "prellbock" and, at least in 2010, there are a variety of others included as built-in items. (I think some of them are used in older routes so they ought to be present on some older versions.) And they do act as a signal in Trainz. They would actually be a full working signal (aka not always be red) except that they're placed at the ends of the track so that causes them to always red. If you tried to use one to block off an area that had signaled track on it, that would not work and the train would drive right through it.
I like the cdr buffer type 1. nice red light and easy to find. Just don't place it on the track backwards. I seem to recall you can drive right through it. (I misplaced one on the mainline somehow once and it was invis to the train in one direction and stopped everything dead going the other way. Took me a while to figure that out too. LOL)
Hi mate I use speed retartas on the ends of my traks so that the wagon slows to a stop
I use about 5 in a row as I do a lot of shunting (kicking and slipping)
