Colony ship (World Enough and Time)

A colony ship was travelling from Mondas to pick up colonists. When the ship almost traversed into a black hole, the crew experienced the effects of time dilation, where time on the lowest decks of the ship was travelling faster than on the upper decks.

Layout
The ship was approximately 400 miles long and around 100 miles wide.

Decks
The ship contained over a thousand decks, each of which presented a Mondasian environment. These included:
 * 0 - The main control deck.
 * 507 - A deck containing the largest of the ship's solar farms.
 * 1056 - An urban deck, containing various apartment blocks and a hospital.
 * Other floors mentioned on the lift scanner are: 1052, 1051, 1050, 1049, 1048, 1047, 1046, 1045, 1044, 1043, 1042, 1041, 1040, 1039, 1038, 1037, 1036, 1035, 1034, 1033, 1032, 1031, 1030, 1029, 1028, 1027, 1026, 1025, 1024, 1023, 1022, 1021, 1020, 1019, 1018, 1017, 1016, 1015, 0951, 0950, 0949, 0948, 0947, 0946, 0945, 0944, 0943, 0942, 0941, 0940, 0939, 0938, 0937, 0936, 0935, 0934, 0933, 0932, 0931, 0930, 0929, 0928, 0927, 0926, 0925, 0924, 0923, 0922, 0921, 0920, 0919, 0918, 0917, 0916, 0915, 0914, 0913, 0912, 0911, 0910, 0909, 0908, 0907, 0906, 0905, 0904, 0903, 0902, 0901, 0900, 0899, 0898, 0897, 0896, 0895, 0894, 0893, 0892, 0891, 0890, 0889, 0888, 0887, 0886, 0885, 0884, 0737, 0736, 0735, 0734, 0733, 0732, 0731, 0730, 0729, 0728, 0727, 0726, 0725, 0724, 0723, 0722, 0721, 0720, 0719, 0718, 0717, 0716, 0715, 0714, 0713, 0712, 1711, 0710, 0709, 0708, 0707, 0706, 0705, 0704, 0703, 0702, 0701, 0700, 0699, 0698, 0697, 0696, 0695, 0694, 0693, 0692, 0691, 0690, 0689, 0688, 0687, 0686, 0685, 0684, 0683, 0682, 0681, 0680, 0679, 0668, 0667, 0666, 0665, 0664, 0663, 0662, 0661, 0660, 0659, 0658, 0657, 0656, 0655, 0654, 0653, 0652, 0651, 0650, 0649, 0648, 0647, 0646, 0645, 0644, 0643, 0493, 0492, 0491, 0490, 0489, 0488, 0487, 0486, 0485, 0484, 0483, 0482, 0481, 0480, 0479, 0478, 0477, 0476, 0475, 0474, 0473, 0472, 0031, 0030, 0029, 0028, 0027, 0010, 0009, 0008 and 0007.

Each level from the bottom and up would move a little slower than the one below it due to the black hole.

Crew
At take off, there were fifty crew members aboard the ship. They included Jorj: a member of janitorial staff. Following the effects of time dilation, the ship became filled with generations of lifeforms, each descended from the ship's crew.

Technology
The ship was fitted with super-fast inertia lifts and was propelled by rear thrusters. Aboard the lowest decks, evolution of technology was advanced. In order to adapt to expiring environments, an artificial evolution was devised. The Mondasian inhabitants were gradually upgraded into Cybermen. (TV: World Enough and Time)
