Yes. Edit the config.txt file in the interior kuid to place or change a camerlist container. The coordinates for each position are for left/right, front/back, up/down, yaw and pitch. To determine these variables add -freeintcam to the TRS2006\trainsoptions.txt file. Pan around the interior using arrow keys and mouse. The coordinates will be displayed at the bottom-left of the screen. Make sure to include the minus sign were appropriate.
