Just like people post a: "Test Thread" just to see if it actually shows up on the Forum ... Some spend a 1/2 hour laying track with so sharp of curves, that a trolley could not negotiate the super tight curves and sharp turnouts ... and they want to quickly see whether it actually uploads onto the DLS ... Others see their 3 - 1/4 whole days work, as an absolutely wondrous masterpiece, a completed finished work of art
I do agree with you, but since I first downloaded Trainz, I've been looking a lot more closely at real railway lines, and I was surprised to find that there are, in fact, some very tight bends. In addition, I had been worried that some of my gradients are steep, but once again I find that in real life (with electric power) our city* trains take on some very steep gradients.
