Knowing that you're brand new, no one will be expecting miracles. You will become faster over time without compromising safety, especially when you become familiar with the characteristics of certain lines and yards. Remember you're posting with people who have picked up many bad habits and become complacent over the years. If you split a switch, derail, collide, miss a handbrake, or get to your first stop and doors won't open because you never checked them, you'll be going downtown to face severe penalties. You may also be taking a handswitchmen, tower op or c/r down with you. Do your job the way you're supposed to do it. You here someone telling you about all the stuff they don't do, tell yourself that you're going to do it anyway because it's how you were trained and put them out of your mind.
