This depends on how you define your axes. Let's assume they're defined as normal (being positive is accelerating, negative is breaking, and for velocity positive is driving forward, negative is driving in reverse). Then of course, you are speeding up. This simply means the train was in reverse, but it's accelerating in the positive direction now.
False. An object is slowing down when its speed is decreasing, which means it is decelerating, not accelerating in the direction of motion.
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
A car can be slowing down while still accelerating if its speed is decreasing but the direction of its velocity is changing. For example, if a car is moving in a curve, its speed may be decreasing but it is still accelerating towards the center of the turn. This is known as centripetal acceleration.
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
An object that is accelerating may be slowing down, gaining speed, and changing direction.
No, when anything is slowing down it is decelerating.
False. An object is slowing down when its speed is decreasing, which means it is decelerating, not accelerating in the direction of motion.
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
Could be bad u-joints in the driveshaft.

You may be referring to Train Train by Blackfoot.
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
No. Negative acceleration simply means it is accelerating in a particular direction.
One tire has a belt separation.
Yes it has negative acceleration, which is acceleration in the opposite direction of travel. It is called deceleration.
Could be a turbocharger, or a low oil level in a manual transmission causing it to "howl".
