I just thought this was a neat picture. A dimly lit caboose, heading into a tunnel, noisily clanking away with the rest of the rolling stock. The bright red cabooose color contrasts wonderfully with the cool, muted earth tones of the Olson Displays Tunnel.
Yes, I know the tunnel has a little overhang. It's to remind me to expand the layout sooner rather than later. It's so stable (both the layout and the tunnel) it won't budge one iota.
