When the Serie 6 Ten-wheelers delivered in 1906-1907 were superheated in later decades, only 5 remained compounds; those appear in Locobase 11238.
The other 35 were given 2 19" x 26" cylinders and fell into three sub-groups depending on valve motion. The Class 10 shown here used the Gooch motion first made famous on Britain's Great Western Railway. The 600-series engines that comprised Serie 10 were, in order of their new numbering of 1000 to 1014: 632, 638 (1928); 601-603, 628 (1929); 605, 637, 615 (1930); 616 (1931); 633, 626 (1938); 611 (1937); 627 (1931); and 621 (1930).
All other specifications were the same as the other Serie 10 modifications except for slight differences in weight. See 11240 for those that were fitted with Walschaert radial valve gear (Serie 10A) and 11241 for the 10 that retained Stephenson link motion.

As noted in 11239, most of the Serie 6 Ten-wheelers, which were delivered as cross-compounds in 1906-1907, were converted to simple expansion and superheated.
The program created three sub-classes based on the valve motion adopted. Serie 10 engines had Gooch valve gear, Serie 10A - this entry - used Walschaert radial valve gear mounted outside, and Serie 10B retained the original Stephenson link motion.
Unlike the Serie 10, most of which were converted in the late 1920s and early 1930s, the 10As all were updated after World War Two. In order of their later road numbers, the Serie 6 locomotives converted were:
600 (November 1947)
604 (October 1947)
606 (September 1947)
608 (April 1947)
610 (December 1945)
613 (October 1947)
614 (April 1946)
618 (November 1948)
620 (June 1945)
621 (March 1947)
623 (November 1947)
629 (March 1946)
635 (April 1947)
636 (September 1946), and
696 (May 1946).
All other specifications were the same as the other Serie 10 modifications except for slight differences in weight. See 11240 for those that were fitted with Walschaert radial valve gear (Serie 10A) and 11241 for the 10 that retained Stephenson link motion.

Series 10B engines were converted last of all, receiving their superheaters in 1951-1954 In order of their later road numbers, the Serie 6 locomotives converted were:
607, 609, 612, 617, 619, 622, 624-625, 630, 634, 695, 697-699
All other specifications were the same as the other Serie 10 modifications except for slight differences in weight. See 11240 for those that were fitted with Walschaert radial valve gear (Serie 10A) and 11239 for the 10s that operated Gooch valve gear.

At least in its superheated version, this subset of a large class of cross-compound Ten-wheelers seems to have been identical to the Serie 3 Consolidations shown in Locobase 11231. The only differences were in the amount of adhesive weight (to be expected since one less axle was available) and the height of the drivers.
Only these 5 - 1 BP, 2 NBLC, 2 BLW -- remained cross-compounds; the others all were converted to simple expansion. See Locobase 11239.
